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.

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.

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.

PiperOrigin-RevId: 329510552 -- e327e54b805d67556f934fa7f7dc2d4e72fa066a by Abseil Team <absl-team@google.com>: Fix -Wsign-compare issues. These lines could theoretically have overflowed in cases of very large stack traces etc. Very unlikely, but this was causing warnings when built with -Wsign-compare, which we intend to enable with Chromium. In none of these three cases is it trivial to switch to a range-based for loop.

-- 0c8282d75798c77733eee6167870bcc6acc0bfc1 by Evan Brown <ezb@google.com>: Provide mutable access to the key in node handles using std::launder when compiled with C++17 or later. Also, document why we can't provide mutable access to the key without C++17. Note: we use Policy::mutable_key() because btree already uses Policy::key() internally to get const key access, and we want to avoid calling std::launder unless we need mutable access to the key.

PiperOrigin-RevId: 326471847 -- 87a7644864ba7c003b0611898aaba1b71c840376 by Abseil Team <absl-team@google.com>: Avoid a costly divide (the division accounts for 10% of the time spent in the function). When the division is signed, the compiler has to generate a div. When it is unsigned, it can generate a shift: https://godbolt.org/z/vGfTv4. As per the test above the div, we know that the value is unsigned.
