  [DirectX] Remove custom error classes from RootSignature Metadata parser  (#161921)

We have too many custom error classes that look too much alike when
error handling root signature metadata parser. This PR removes those
custom error classes and instead reuses `StringError` and a few
pre-formatted error messages.

Closes: [#159429](https://github.com/llvm/llvm-project/issues/159429)

  [WebAssembly] recognize saturating truncation (#155470)

fixes https://github.com/llvm/llvm-project/issues/153838
using the same approach as
https://github.com/llvm/llvm-project/pull/155377

Recognize a manual saturating truncation and select the corresponding
instruction. This is useful in general, but came up specifically in
https://github.com/rust-lang/stdarch because it will allow us to drop
more target-specific intrinsics in favor of cross-platform ones.

  [Clang] Wire up -fsanitize=alloc-token (#156839)

Wire up the `-fsanitize=alloc-token` command-line option, hooking up
the `AllocToken` pass -- it provides allocation tokens to compatible
runtime allocators, enabling different heap organization strategies,
e.g. hardening schemes based on heap partitioning.

The instrumentation rewrites standard allocation calls into variants
that accept an additional `size_t token_id` argument. For example,
calls to `malloc(size)` become `__alloc_token_malloc(size, token_id)`,
and a C++ `new MyType` expression will call
`__alloc_token__Znwm(size, token_id)`.

Currently untyped allocation calls do not yet have `!alloc_token`
metadata, and therefore receive the fallback token only. This will be
fixed in subsequent changes through best-effort type-inference.

One benefit of the instrumentation approach is that it can be applied
transparently to large codebases, and scales in deployment as other
sanitizers.

Similarly to other sanitizers, instrumentation can selectively be
controlled using `__attribute__((no_sanitize("alloc-token")))`. Support
for sanitizer ignorelists to disable instrumentation for specific
functions or source files is implemented.

See clang/docs/AllocToken.rst for more usage instructions.

This PR includes only one of the fxdivi functions (rdivi). It uses a
polynomial function for initial approximation followed by 4
newton-raphson iterations to calculate the reciprocal and finally
multiplies the numerator with it to get the result.
