Add IsDataEdge() and DataEdgeValue() helper functions.
This moves repetitive logic accessing data edges into its own header, and more strongly defines the notion of what a data edge is, enforcing the internal invariants. This will also be incorporated in optimized Cord iteration logic once CordRepConcat is totally removed from the Cord code.

It should have been ABSL_HAVE_CPP_ATTRIBUTE(nodiscard) instead of
ABSL_HAVE_ATTRIBUTE(nodiscard). As a result, some code is not

test.
Recommend that C++17-only code use the standard [[nodiscard] directly.

Prevent compiler from optimizing Group_Match* benchmarks away.
Currently we benchmark single store of precomputed value.
Not all affected benchmarks show performance changes:
BM_Group_Match 0.53ns ± 1% 0.53ns ± 0% -0.42% (p=0.038 n=10+10)
BM_Group_MatchEmpty 0.26ns ± 1% 0.26ns ± 1% ~ (p=1.000 n=10+10)
BM_Group_MatchEmptyOrDeleted 0.26ns ± 1% 0.26ns ± 1% ~ (p=0.121 n=10+10)
BM_Group_CountLeadingEmptyOrDeleted 0.26ns ± 1% 0.45ns ± 0% +70.05% (p=0.000 n=10+8)
BM_Group_MatchFirstEmptyOrDeleted 0.26ns ± 0% 0.44ns ± 1% +65.91% (p=0.000 n=8+9)
But inspecting the generated code shows the difference,
e. g. BM_Group_MatchFirstEmptyOrDeleted
Before:
add $0xffffffffffffffff,%rbx
jne 30
After:
pcmpeqd %xmm0,%xmm0
pcmpgtb -0x30(%rbp),%xmm0
pmovmskb %xmm0,%eax
add: 0x23$0xffffffffffffffff,%rbx

Make Cord::InlineRep::set_data unconditionally zero out memory.
Currently there is a single case where we don't zero out memory
as an optimization. Unconditional zeroing doesn't show any changes
in benchmarks, except for the unrelated improvement:
BM_CordPartialCopyToCord/1M/1 12.6ns ± 4% 12.6ns ± 4% ~ (p=0.857 n=16+19)
BM_CordPartialCopyToCord/1M/128 44.9ns ± 7% 45.0ns ± 3% ~ (p=0.468 n=18+17)

BM_CordPartialCopyToCord/1M/16k 193ns ± 6% 168ns ± 6% -13.17% (p=0.000 n=17+17)
BM_CordPartialCopyToCord/4M/16k 199ns ± 4% 177ns ± 4% -11.36% (p=0.000 n=17+18)
BM_CordPartialCopyToCord/4M/32k 275ns ± 3% 250ns ± 4% -9.00% (p=0.000 n=18+18)
BM_CordPartialCopyToCord/4M/64k 291ns ± 4% 266ns ± 5% -8.53% (p=0.000 n=18+16)
BM_CordPartialCopyToCord/4M/128k 322ns ± 5% 291ns ± 4% -9.43% (p=0.000 n=20+18)
BM_CordPartialCopyToCord/8M/32k 281ns ± 5% 251ns ± 4% -10.38% (p=0.000 n=20+16)
BM_CordPartialCopyToCord/8M/64k 293ns ± 6% 267ns ± 4% -8.87% (p=0.000 n=16+19)
BM_CordPartialCopyToCord/8M/128k 334ns ± 3% 305ns ± 2% -8.56% (p=0.000 n=17+16)
This is clearly an alignmnet effect since number of the executed instructions is the same:
M_CordPartialCopyToCord/1M/1 155 ± 0% 155 ± 0% ~ (all samples are equal)
BM_CordPartialCopyToCord/1M/128 446 ± 0% 446 ± 0% ~ (p=0.332 n=36+39)
BM_CordPartialCopyToCord/1M/1k 473 ± 0% 473 ± 0% ~ (p=0.969 n=40+40)
BM_CordPartialCopyToCord/1M/8k 808 ± 0% 808 ± 0% ~ (p=0.127 n=40+39)
BM_CordPartialCopyToCord/1M/16k 957 ± 0% 957 ± 0% ~ (p=0.532 n=40+40)
BM_CordPartialCopyToCord/4M/16k 952 ± 0% 952 ± 0% ~ (p=0.686 n=39+39)
BM_CordPartialCopyToCord/4M/32k 1.12k ± 0% 1.12k ± 0% ~ (p=0.690 n=40+40)
BM_CordPartialCopyToCord/4M/64k 1.23k ± 0% 1.23k ± 0% ~ (p=0.182 n=40+39)
BM_CordPartialCopyToCord/4M/128k 1.44k ± 0% 1.44k ± 0% ~ (p=0.711 n=40+40)
BM_CordPartialCopyToCord/8M/32k 1.12k ± 0% 1.12k ± 0% ~ (p=0.697 n=40+40)
BM_CordPartialCopyToCord/8M/64k 1.23k ± 0% 1.23k ± 0% +0.00% (p=0.049 n=40+40)
BM_CordPartialCopyToCord/8M/128k 1.44k ± 0% 1.44k ± 0% ~ (p=0.507 n=40+40)
This makes code simpler and doesn't regress performance.

debugging: add support for non-glibc targets for debugging
This relaxes the ELF mem_image handling and subsequently enables the VDSO
support for non-glibc targets. The primary need for the restriction was the
use of the `__GLIBC_PREREQ` macro. If it is undefined, assume that the glibc
pre-requisite is unavailable. This allows building the debugging_internal
target on musl targets.

Alternative bit mixer for LowLevelHash on ARM
LowLevelHash's bit-mixer is inefficient on ARM because it calculates a 128-bit product of two 64-bit numbers. On ARM, this requires a sequence of two instructions with a high combined latency and poor throughput. This change provides alternative bit-mixing code for ARM that uses only 64-bit arithmetic (multiplication, xor, and left-shifts) and speeds things up considerably.
The bit-mixing code for ARM was inspired by by Woothash[1] and xxh3[1]. Once I landed on a sequence of operations that provided good mixing, I used a test harness to search for the combination of shift / rotate factors that provided the best mixing, as indicated by SMHasher hash quality tests. The new mixing code passes 13 out of 15 of the hash quality test suites in SMHasher, with the two failures being in the noise range: e.g. 1 collision vs. zero expected in a keyset of ~8m keys.

Change Cord constructor(string_view) to explicit make_tree and Cordz tracking

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.

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.

demangler to allow "_" with the alphanumeric string.
Please refer to libiberty's cp-demangle.c where function d_clone_suffix

1. '_' is accepted as a valid character with the alphanumeric sequence.
2. The alphanumberic sequence is optional.
3. The digit sequence is optional.

In that case, we are supposed to extract the first such key in the container - [reference](https://en.cppreference.com/w/cpp/container/multiset/extract), but we were extracting the first one we found (which was not necessarily the first in the container).

Add flag for 'shallow subcord' feature for experimental ring buffer rollout
There is a potential trade-off of CPU cost vs over-sharing cord data for subcord of large cords. This flag allows making subcords shallow for ringbuffers (with a potential larger waste of referenced source cords), which allows us to make subcord fast for this apps that do no persist (unmodified / plain copied) sub cords.
This change also introduces constants for the default settings, intended to keep the internal cord settings concistent with external flags.

Improve cache-locality for ThreadIdentity and PerThreadSynch.
This is a change based on an observation in RPC benchmarks that shows
significant cycles being spent in waking up a thread, 99.8% of which
was on cache misses. Investigating this a bit more, it turns out to
be due to sharing the cache line with the waiter state.
To fix this issue, the following changes are introduced:
- Reorder fields in PerThreadSync so that it fits in a single cache line
The size of this structure was 80 bytes before this change.
Note: Manually inspected all booleans to make sure they are not modified by
multiple threads concurrently.

On macOS, `mem_alloc` is defined like this:
rpc/types.h:86:#define mem_alloc(bsize) calloc(1, bsize)
So if that file is included before container_memory.h, the variable mem_alloc
may never get defined. This is fixed by using a different name.

Re-write the logic for detecting which stacktrace implementation to use on Linux.
The visible change is to detect the presence of the `<execinfo.h>`
header, which allows using the `backtrace`-based implementation when
it is available.
The logic has been simplified as well.
