  Effects: Inserts the text representation for charT of id into out.

This wording changed in C++23 due to adding a formatter specialization for

This issue is that thread::id is an integral or pointer and affected by the
formatting manipulators for them. Thus the text representation can differ if
x == y which violates the requirements.

The fix has to hard-code some formatting style for the text
representation. It uses the Standard specified default values

[libc++] Set correct size at the end of growing std::string

This commit deprecates `std::basic_string::__grow_by`, which is part of ABIv1. The function is replaced by `std::basic_string:__grow_by_without_replace`, which is not part of ABI.

- The original function `__grow_by` is deprecated because it does not set the string size,  therefore it may not update the size when the size is changed, and it may also not set the size at all when the string was short initially. This leads to unpredictable size value. It is not removed or changed to avoid breaking the ABI.
- The commit adds `_LIBCPP_HIDE_FROM_ABI`  guarded by `_LIBCPP_ABI_VERSION >= 2` to `__grow_by`. This allows the function to be used in the dylib in ABIv1 without raising the `[abi:v170000]` error and removes it from future ABIs. `_LIBCPP_HIDE_FROM_ABI_AFTER_V1` cannot be used.
- Additionally, `__grow_by` has been removed from `_LIBCPP_STRING_UNSTABLE_EXTERN_TEMPLATE_LIST` in `libcxx/include/__string/extern_template_lists.h`.

This bugfix is necessary to implement string ASan annotations, because it mitigates the problems encountered in D132769.

[LangRef] vscale_range implies the vscale is power-of-two

According the discuss on D154953, we need to make the LangRef change
before the optimization relied on the new behaviour:
      vscale_range implies vscale is a power-of-two value, parse of the
  attribute to reject values that are not a power-of-two.

Thanks nikic for the wonderful summary of discussing on D154953:
To provide a bit more context here. We would like to have power of two vscale exposed in a target-independent way, so we can make use of this in places like ValueTracking, just like we currently do the vscale range. Some options that have been discussed are:
  - Remove support for non-power-of-two vscales entirely. (This is my personal preference, but this is hard to undo if it turns out someone does need them.)
  - Add an extra attribute vscale_pow2, or a data layout property.
  - Make vscale_range imply power-of-two vscale, as a compromise solution (what this patch does). This would be relatively easy to turn into one of the two above at a later point.

[llvm-objdump] Create ObjectFile specific dumpers

We pay the one-off boilerplate overhead to create `*Dumper` classes that derive
from objdump::Dumper a la llvm-readobj. This has two primary advantages.

First, a lot object file format specific code can be moved from
llvm-objdump.cpp to *Dump.cpp files. Refactor `printPrivateHeaders` as
an example.

Second, with the introduction of ELFDumper<ELFT>, we can simplify
a few dispatch functions in ELFDump.cpp.

In addition, the ObjectFile specific dumpers contains a ObjectFile specific
reference so that we can remove a lot of `cast<*ObjectFile>(Obj)`.

to 64 bits then extract either bits [63:32] or [62:31].

Unfortunately, without Zba we need to use 2 shifts for the
zero extends. These can be optimized out later if the producing
instruction already zeroed the upper bits or if we can use lwu.

There are alternative sequences we can use for clmulh/clmulr
when the zero extend isn't free, but those are best handled by
a DAG combine to give the best opportunity for removing the extend.
