[libc++][ranges]Refactor `copy{,_backward}` and `move{,_backward}`
Instead of using `reverse_iterator`, share the optimization between the 4 algorithms. The key observation here that `memmove` applies to both `copy` and `move` identically, and to their `_backward` versions very similarly. All algorithms now follow the same pattern along the lines of:
```
if constexpr (can_memmove<InIter, OutIter>) {
memmove(first, last, out);
} else {
naive_implementation(first, last, out);
}
```
A follow-up will delete `unconstrained_reverse_iterator`.
This patch removes duplication and divergence between `std::copy`, `std::move` and `std::move_backward`. It also improves testing:
- the test for whether the optimization is used only applied to `std::copy` and, more importantly, was essentially a no-op because it would still pass if the optimization was not used;
- there were no tests to make sure the optimization is not used when the effect would be visible.

[Clang][AArch64] Support AArch64 target(..) attribute formats.

with the GCC implementation from
https://gcc.gnu.org/onlinedocs/gcc/AArch64-Function-Attributes.html#AArch64-Function-Attributes.
The supported formats are:
- "arch=<arch>" strings, that specify the architecture features for a
function as per the -march=arch+feature option.
- "cpu=<cpu>" strings, that specify the target-cpu and any implied
atributes as per the -mcpu=cpu+feature option.
- "tune=<cpu>" strings, that specify the tune-cpu cpu for a function as
per -mtune.
- "+<feature>", "+no<feature>" enables/disables the specific feature, for
compatibility with GCC target attributes.
- "<feature>", "no-<feature>" enabled/disables the specific feature, for
backward compatibility with previous releases.
To do this, the parsing of target attributes has been moved into
TargetInfo to give the target the opportunity to override the existing
parsing. The only non-aarch64 change should be a minor alteration to the
error message, specifying using "CPU" to describe the cpu, not
"architecture", and the DuplicateArch/Tune from ParsedTargetAttr have

Profile matching and IR annotation for memprof profiles.
See also related RFCs:
RFC: Sanitizer-based Heap Profiler [1]
RFC: A binary serialization format for MemProf [2]
RFC: IR metadata format for MemProf [3]*
* Note that the IR metadata format has changed from the RFC during
implementation, as described in the preceeding patch adding the basic
metadata and verification support.
The matching is performed during the normal PGO annotation phase, to
ensure that the inlines applied in the IR at that point are a subset
of the inlines in the profiled binary and thus reflected in the
profile's call stacks. This is important because the call frames are
associated with functions in the profile based on the inlining in the
symbolized call stacks, and this simplifies locating the subset of
profile data relevant for matching onto each function's IR.
The PGOInstrumentationUse pass is enhanced to perform matching for
whatever combination of memprof and regular PGO profile data exists in
the profile.
Using the utilities introduced in D128854:
The memprof profile data for each context is converted to "cold" or
"notcold" based on parameterized thresholds for size, access count, and
lifetime. The memprof allocation contexts are trimmed to the minimal
amount of context required to uniquely identify whether the context is
cold or not cold. For allocations where all profiled contexts have the
same allocation type, no memprof metadata is attached and instead the
allocation call is directly annotated with an attribute specifying the
alloction type. This is the same attributed that will be applied to
allocation calls once cloned for different contexts, and later used
during LibCall simplification to emit allocation hints [4].
Depends on D128141 and D128854.

costs impose an ordering on eviction candidates. I also feel that there
is a bit of an impedance mismatch as the actual costs occure when
encoding instructions using those registers, but the order of VReg
assignments is not primarily ordered by number of Defs+Uses.

[lld-macho] Do not error out on dead stripped duplicate symbols
Builds that error out on duplicate symbols can still succeed if the symbols

In order to provide an easier to path for adoption, introduce a new flag that will

[libc++] Fix ADL for `make_error_{code,condition}`
Implement LWG 3629, by making lookup for make_error_code and
make_error_condition only consider names found by ADL. This is achieved
by adding a block scope using-declaration for a function that will be
found by unqualified lookup, preventing unqualified lookup from
continuing to enclosing scopes (the class scope, then enclosing
namespaces). The function named by the using declaration is not
viable, so overload resolution must select a candidate found by ADL.

[mlir][vector] Fix double rank reducing folding bug
In https://reviews.llvm.org/D133883, we changed the
`FoldExtractSliceIntoTransferRead` pattern from requiring
full identity map to minor identity map. This effectively
allows rank reducing `vector.transfer_read` ops. However,
the logic for checking `tensor.extract_slice` rank reducing
still looks at the vector rank, which now could be smaller
than the `tensor.extract_slice`'s output tensor rank.
It ends up we can have incorrect index cacluation after
folding due to this double rank reducing behavior.
