This change introduces the symbol
ABSL_INTERNAL_NEED_REDUNDANT_CONSTEXPR_DECL
to guard redundant declarations of static constexpr data
members that are needed prior to C++17.
This change also introduces the symbol
ABSL_INTERNAL_CPLUSPLUS_LANG, which is supposed to be set
to the same value as __cplusplus, except it uses _MSVC_LANG
on MSVC so that the value is correct on MSVC.
Neither of these new symbols should be used outside of Abseil.
Fixes#1191

Omit any changes to cctz for now, because it's vendored from another project.

Inline CycleClock code and remove branch for x86 CycleClockSource function
This CL removes the relaxed load for x86 as there is no acquire price to pay on x86. It inlines the UnscaledCycleClock::Now() which is a single RTDSC op for x86, and likewise inlines CycleClock::Now() for x86. The inlining should mostly have secondary benefits such as reducing spills on outlined calls.
LTO may eventually hoist these functions inline for the hotspots, but it doesn't hurt to default inline this for all builds and let the compiler decide on the first pass.
The perlab benchmark is noisy for the plain BM_Now, but the other benchmarks and the run on my local machine are clear.

Small refactoring to work towards allowing for node_btree_* containers.
- Change common_params::transfer to rely on slot_policy transfer instead of manually doing construct/destruct. Transfer is not construct/destruct for node containers.
- Move maps' value_compare into btree.h from btree_map.h so it can be reused for node_btree_map.h.
- Also add a test for maps' value_compare protected members.

Correct the computation of contention cycles
Currently, we record contention cycles from the first time a thread started
waiting on a mutex. Consider a situation in which two threads, T1 and T2, run
a loop at the top of which they acquire a common mutex and release it at the
end of the loop body. Further assume that T2 is never able to acquire the
mutex as T1 repeatedly acquires and then releases the mutex. In this case, we
would expect that the reported contention cycles would be increase linearly
over time. But currently we observe a quadratic behavior in the reported
waiting time as mentioned in b/14684244#comment10.
To fix the issue, this CL records the contention cycles experienced by all the threads woken up when the mutex is released. Further, contention_start_cycles is set to the current time since the contention cycles for the time already passed has been taken into account. With this CL, we get a linear increase in the waiting time, the expected behavior.

`rint` differs from `round` in that it uses the current FPU rounding
mode. It’s thus potentially faster, since it doesn’t have to save and
restore FPU state. It also is more reflective of developer intent –
most developers expect all FPU operations to use the current rounding
mode, and having exponential_biased follow that rule seems ideal.

Rename absl::hash_internal::HashState to absl::hash_internal::MixingHashState.
Before this change, we had two classes named HashState: absl::HashState, the public API used for type erasure, and absl::hash_internal::HashState, the internal concrete implementation ordinarily used.
The internal class used to be named `CityHashState`, but we renamed it to `HashState` it when we changed underlying hash implementation to wyhash. This inadvertent naming conflict made the code much harder to read, and this change intends to undo that.

Improve speed of BlockingCounter by making its most common path lock free.
With the new implementation, the fast path of BlockingCounter::DecrementCount()
is only a fetch_sub operation. This is most times much more efficient than the
previous implementation (full mutex lock/unlock). As a matter of fact, in most
actual usecases in practice, the waiter thread is already waiting on the
Wait() call when DecrementCount() is called, which makes Mutex::Unlock() take
the slow path as there's a waiter thread that it might need to wake up.

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.

Move CordRep Ref() and Unref() logic into cord_internal.h
This change moves Ref() and Unref() logic out of cord.cc into cord_internal. The main purpose is to make upcoming ring buffer changes easier to isolate from existing cord.cc code. Notice that this removes the nullptr check from Unref() and now requires it to be non null (which held true most times). We may need to rethink if the 'unref unlikely one' is the common case: are cordreps most likely shared? This may be something between 'root' and non root nodes, i.e., is it more likely for leaf / flat nodes in large cords to be shared than top level cordreps being shared? Vice versa? Benchmarks say that we mostly shouldn't care, the caveat being that atomic ops seem more expensive on upcoming archs (arcadia) so we should error on the side of an extra IsOne() branch saving us single owned atomic ops.

Simplify unaligned memory access functions.
The #ifdef to produce calls to __sanitizer_unaligned_load16 etc were needed in past versions of this code, when we were lying to the compiler about the alignment of the loads/stores, by using a reinterpret_cast.
However, a year ago, absl switched to simply use memcpy. Sanitizers support this correctly by default, nothing extra is required.

Add `absl_btree_prefer_linear_node_search`
Allow keys of `btree_set`, `btree_map`, `btree_multiset`, and `btree_multimap`
to opt-in to linear search (instead of binary search). Linear search was
used previously for arithmetic types with `key_compare` of `std::greater`
or `std::less`.
For example, this would be useful for key types that wrap an integer
and define their own cheap `operator<()`.
```
class K {
public:
using absl_btree_prefer_linear_node_search = std::true_type;
...
private:
friend bool operator<(K a, K b) { return a.k_ < b.k_; }
int k_;
};
absl::btree_map<K, V> m; // Uses linear search
assert((absl::btree_map<K, V>::testonly_uses_linear_node_search()));

The STL exception functions are not present in the Android NDK, so Abseil fails to build as part of ANGLE in AOSP.

Update Abseil's internal Invoke() implementation to follow C++17 semantics.
Starting in C++17, when invoke'ing a pointer-to-member, if the object representing the class is a reference_wrapper, that wrapper is unpacked. Because we implement a number of functional APIs that closely match C++ standard proposals, it is better if we follow the standard's notion of what "invoking" means.
This also makes `absl::base_internal::Invoke()` match `std::invoke()` in C++17. I intend to make this an alias in a follow-up CL.

Change many distribution tests to use pcg_engine as a deterministic source of entropy.
It's reasonable to test that the BitGen itself has good entropy, however when testing the cross product of all random distributions x all the architecture variations x all submitted changes results in a large number of tests. In order to account for these failures while still using good entropy requires that our allowed sigma need to account for all of these independent tests.
Our current sigma values are too restrictive, and we see a lot of failures, so we have to either relax the sigma values or convert some of the statistical tests to use deterministic values.
This changelist does the latter.
