Change Cord constructor(string_view) to explicit make_tree and Cordz tracking
This CL changes the ctor to use an easier to maintain model where Cord code explicitly invokes Cordz update or new / tree logic, which avoids the ambiguity of the 'branched' InlineRep::set_tree code. This removes the need to equip InlineRep with 'MethodIdentifier' or other necessary call info, and also is a cleaner model: InlineRep is carrying too much code now that should plainly sit in Cord, especially with all internal abstractions having moved to InlineData.

Rename the 'Compare' template type to 'LessThan', as the passed-in function is expected to act like operator<. It is worth avoiding confusion with std::compare, which returns an int (-1/0/1), as due to implicit casting this can lead to hard-to-spot bugs.

Replace mutex() with Lock() / Unlock() function
Mini design future tracking of CordzInfo sampled cords: CordzInfo holds a CordRep* reference without a reference count. Cord is responsible for synchronizing updates for sampled cords such that the CordRep* contained in CordzInfo is at all times valid. This is done by scoping Lock() and Unlock() calls around the code modifying the code of a sampled cord. For example (using the future CL CordzUpdateScope()):
CordzInfo* cordz_info = get_cordz_info();
CordzUpdateScope scope(cordz_info, CordzUpdateTracker::kRemovePrefix);
CordRep* rep = RemovePrefixImpl(root);
set_tree(rep);
if (cordz_info) {
cordz_info->SetCordRep(rep);
}
On CordzInfo::Unlock(), if the internal rep is null, the cord is no longer sampled, and CordzInfo will be deleted. Thus any update resulting in the Cord being inlined will automatically no longer be sampled.

Correct Thumb function bound computation in the symbolizer
On 32-bit ARM, all functions are aligned to multiples of two bytes, and
the lowest-order bit in a function’s address is ignored by the CPU when
computing branch targets. That bit is still present in instructions and
ELF symbol tables, though; it’s repurposed to indicate whether the
function contains ARM or Thumb code. If the symbolizer doesn’t ignore
that bit, it will believe Thumb functions have boundaries that are off
by one byte, so instruct the symbolizer to null out the lowest-order bit
after retrieving it from the symbol table.

Add a `rep` property to CordzInfo to be managed by Cord logic.
This change adds a `rep` property to CordzInfo, which is intended to be used by collection logic.
Mini design:
Cord invokes TrackCord() providing the active 'root' cordrep of the newly sampled Cord, returning a CordzInfo with a weak (uncounted) reference to this root. Cord invokes `SetCordRep()` each time the root cordrep of the sampled Cord is updated while holding `mutex()`. Cord must also obtain `mutex()` _before_ removing a reference on the old root. i.e.: Cord must guarantee that the (weak) reference held in CordzInfo is at all times valid.
CordzInfo collection code can then safely obtain a (reference counted) rep pointer by adding a reference to `rep_` while holding `mutex()`. This requires only a very brief critical section inside CordzInfo logic, minimizing contention with concurrent Cord updates.
Cord code should typically obtain and hold `mutex()` for the entirety of each mutating Cord operation on a sampled cord. As Cord is thread compatible, it never competes on the lock with any other thread. The only possible concurrent access is from Cordz collection code, which should be a relatively rare event.

Fix CordRepRing diabolical growth
The 'Mutable' function in CordRepRing was over-eager in doubling capacity, which lead to 'ludicrous' growth in the diabolical test case as added to cord_test. This CL fixes the doubling for growing shared reps, and tempers CordRepRing growth for non shared capacity to 1.5 instead of 2, which is more inline with a conservative growth we also have in tree cord.
After this change, CordRepRing no longer swamps the heap into the shadow realm, and is in effect reducing the memory used compared to the tree implementation. With a diabolical 5000 bytes growth pattern:
Tree cord: 1523520 bytes
Ring cord: 274232 bytes

Accept e.g. ".__uniq" as a valid clone name. Further, bring the implementation
on par with libiberty's demangler grammar.
Clang introduced option -funique-internal-linkage-names that adds the suffix
".__uniq.[0-9]+" to internal linkage functions to give them a globally unique
identifier. The suffix was designed to work with existing demanglers which do
recognize a "_" along with the alphanumeric string. This change enhances the
demangler to allow "_" with the alphanumeric string.
Please refer to libiberty's cp-demangle.c where function d_clone_suffix
implements the demangling of clone suffixes :
1. '_' is accepted as a valid character with the alphanumeric sequence.
2. The alphanumberic sequence is optional.
3. The digit sequence is optional.

Propagate nice/strict/naggy state on absl::MockingBitGen.
Allowing NiceMocks reduces the log spam for un-mocked calls, and it enables nicer setup with ON_CALL, so it is desirable to support it in absl::MockingBitGen. Internally, gmock tracks object "strictness" levels using an internal API; in order to achieve the same results we detect when the MockingBitGen is wrapped in a Nice/Naggy/Strict and wrap the internal implementation MockFunction in the same type.
This is achieved by providing overloads to the Call() function, and passing the mock object type down into it's own RegisterMock call, where a compile-time check verifies the state and creates the appropriate mock function.

Increase the minimum number of slots per node from 3 to 4. We also rename kNodeValues (and related names) to kNodeSlots to make it clear that they are about the number of slots per node rather than the number of values per node - kMinNodeValues keeps the same name because it's actually about the number of values rather than the number of slots.
Motivation: I think the expected number of values per node, assuming random insertion order, is the average of the maximum and minimum numbers of values per node (kNodeSlots and kMinNodeValues). For large and/or even kNodeSlots, this is ~75% of kNodeSlots, but for kNodeSlots=3, this is ~67% of kNodeSlots. kMinNodeValues (which corresponds to worst-case occupancy) is ~33% of kNodeSlots, when kNodeSlots=3, compared to 50% for even kNodeSlots. This results in higher memory overhead per value, and since this case (kNodeSlots=3) is used when values are large, it seems worth fixing.

Remove the InsertEnd benchmark.
This benchmark has significantly different possible behaviors that can result in misleading metrics. Specifically, we can have a case where we are deallocating the last node in the b-tree in the erase and then allocating a new node in the insert call repeatedly, whereas normally, we end up just inserting/erasing a value from the last node. Also, the name of the benchmark is misleading because it involves an erase and an insert, but the name only mentions the insert.

Stop testing with double-double random variables
On POWER, long double is often represented as a pair of doubles added
together (double-double arithmetic). We’ve already special-cased
double-double arithmetic in a number of tests, but compiler
bugs [1, 2, 3] have now triggered both false positives and false
negatives, which suggests testing with double doubles is unlikely to
yield useful signal. Remove the special casing and detect if we’re on a
double-double system; if so, just don’t test long doubles.

Implement FuzzingBitGen, an adapter which allows existing randomized tests which use absl::BitGenRef to easily integrate with fuzz testing.
I found myself implementing a similar option in our tensorstore project to fuzz test a storage layer and figured that it would be more useful as a common tool with defaults that take the non-random path.
This is similar to the FuzzedDataProvider mechanism which generates random values from a fuzz string, and is used to generate fuzz test inputs, and internally it uses FuzzedDataProvider.
The basic technique used here is to construct mocking lambdas for all of the absl mock distribution configurations, and forwarding the parameters to fuzzing-specific implementations that call into FuzzedDataProvider. The default paths for the distributions are either the bounds or a median value.

Optimize InlineData representation for cord sampling (cordz)
This CL changes InlineData to allow us to store a (future) Cordz Info pointer directly into the inline representation:
- make InlineData a class that provides a public API to set the active union members (tree or chars) and safely access that data.
- change 'tree' and 'profiled' bits to be the 2 least significant bits, allowing us 62 continquous bits for storing a Cordz Info pointer.
