Fix "unsafe narrowing" warnings in absl, 1/n.
Addresses failures with the following, in some files: -Wshorten-64-to-32 -Wimplicit-int-conversion -Wsign-compare -Wsign-conversion -Wtautological-unsigned-zero-compare (This specific CL focuses on .h and win32 .inc files.)

Fix C++17 constexpr storage deprecation warnings
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 PiperOrigin-RevId: 453923908 Change-Id: I1316c52c19fa0c168b93cced0c817e4cb7c9c862 |

Improve the compiler error by removing some noise from it.
The "deleted" overload error is useless to users. By passing some dummy string to the base class constructor we use a valid constructor and remove the unintended use of the deleted default constructor. PiperOrigin-RevId: 452826509 Change-Id: I5430a373c8e7e3a13336d2c42899e0e59444620b |

-- 83e4cdf03a4d702b30e69204060de09e462e23c6 by Greg Falcon <gfalcon@google.com>: Revert the crc addition to RefcountAndFlags, and restore related comments to their original state. In development, the implementation of SetExpectedCrc() changed, and there is no longer a need to track the CRC status in the refcount. Since the distinction between IsOne() and IsMutable() is subtle *and unused*, removing it now can help avoid subtle bugs in the future. This distinction can always be added back later, if it proves necessary. Keep the reserved bit for now; all it costs is one extra mask instruction in the refcount checks, and space for extra state in Cord is always hard to find. PiperOrigin-RevId: 408647038 -- ee67585cf66954176615271f50f8b278119dd138 by Greg Falcon <gfalcon@google.com>: Implement Cord::SetExpectedChecksum() and Cord::ExpectedChecksum(). SetExpectedChecksum() will store a uint32_t out-of-band alongside a Cord's data. This value persists through copies and assignments. Mutating operations on a Cord cause the value to be forgotten. ExpectedChecksum() retrieves the stored value, if present. This API is intended for storing a CRC32C checksum alongside data, allowing checksums to be passed through dataflows and validated at the final step. However, this API is agnostic to the meaning of the stored value. No CRC32C validation is performed by these new APIs. This implementation adds a new CordRep node, CordRepCrc. A CordRepCrc may (currently) only live at the top of a tree. This allows traversal logic to be agnostic to these nodes, instead putting the needed branches at the mutation level. This also implements the property requested from API review, that any mutation is guaranteed to permanently forget the stored CRC.

This uses a RefcountAndFlags bit that was reserved for this purpose, and will be leveraged in a follow-up change to allow attaching checksums to a Cord's value. This change splits RefcountAndFlags::IsOne() into two distinct operations: * IsOne(): This returns true when the associated CordRep is not shared with other threads. This is useful for functions that consume CordRep instances; for example, code that consumes an unshared CordRep can assume ownership of its children without modifying those refcounts. * IsMutable(): This returns true when the associated CordRep reference is not shared with other threads, *and* does not store an associated checksum value. This is useful for functions that modify a CordRep's contents: code may modify the bytes of a mutable-unshared CordRep without fear of races with other threads, or of invalidating a stored checksum. The tricky part of this CL is ensuring that the correct choice between IsMutable() and IsOne() was made at each point. An incorrect application of IsOne() could lead to correctness bugs in the future. Code conditioned on IsOne() may delete the CordRep in question, or assume ownership of its children, but must not modify the CordRep's data without explicitly adjusting the CRC.

Eliminate some byte swapping from randen_slow
Stop swapping bytes when serializing randen_slow’s Vector128 into and

Minor simplification in drop_deletes_without_resize() - save probe_offset outside the lambda.
Also, add some consts, avoid an auto, and use lambda capture by value instead of reference.

Change the "full table!" asserts in raw_hash_set to use `<= capacity` instead of `< capacity`.
If we add support for non-power-of-two-minus-one capacities, this is the correct thing to assert. For example, consider: Group::kWidth = 8, capacity_ = 8, ctrl_ = {kEmpty, 1, 2, 3, 4, 5, 6, 7, kSentinel, kEmpty, 1, 2, 3, 4, 5, 6}. In this case, if we do an unsuccessful lookup with H2 mapping to slot 1, then the first Group will contain {1, 2, 3, 4, 5, 6, 7, kSentinel} so we need to continue to the second Group (at which point seq.index() == 8 == capacity_) to find a kEmpty.
Note: this is a no-op change for now since we never have `capacity % Group::kWidth == 0`.

Change Ring, EXTERNAL and FLAT tag values to be consecutive values
The purpose of this change is to have FLAT = EXTERNAL + 1. Especially in the ring and btree alternative code, there is a common check if a node is a 'plain' edge (EXTERNAL or FLAT), or 'something else'. This change can make that check a single branch, i.e., instead of 'tag == EXTERNAL || tag >= FLAT', we can simply check for 'tag >= EXTERNAL'. Likewise we have some cases where we check for RING, EXTERNAL or FLAT, so we align RING + 1 with EXTERNAL.

Round a double multiplication before casting it to integer
The code
static_cast<int>(x * y)
(for double x and y) performs a double multiplication into a temporary
that, by standard, may have excess precision. The subsequent cast to int
discards the excess precision. However, the cast may examine the excess
precision during conversion, producing surprising results like
static_cast<int>(1.7 * 10) == 16
on certain systems. Correct this case by explicitly rounding 1.7 * 10
before casting it.

-- 9fc37c11b9e46287acef00ee06ed9adcba54dd13 by Greg Falcon <gfalcon@google.com>: 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.

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).
