Revert "[X86] Refine AMX fast register allocation"
This reverts commit c3f95e9197.
This pass breaks using LLVM in a multi-threaded environment by
introducing global state.
Reduces numbers of files built for clang-format from 575 to 449.
Requires two small changes:
1. Don't use llvm::ExceptionHandling in LangOptions. This isn't
even quite the right type since we don't use all of its values.
Tweaks the changes made in:
- https://reviews.llvm.org/D93215
- https://reviews.llvm.org/D93216
2. Move section name validation code added (long ago) in commit 30ba67439 out
of libBasic into Sema and base the check on the triple. This is a bit less
OOP-y, but completely in line with what we do in many other places in Sema.
No behavior change.

Reverts parts of https://reviews.llvm.org/D17183, but keeps the
resetDataLayout() API and adds an assert that checks that datalayout string and
user label prefix are in sync.
Approach 1 in https://reviews.llvm.org/D17183#2653279
Reduces number of TUs build for 'clang-format' from 689 to 575.
I also implemented approach 2 in D100764. If someone feels motivated
to make us use DataLayout more, it's easy to revert this change here
and go with D100764 instead. I don't plan on doing more work in this
area though, so I prefer going with the smaller, more self-consistent change.

This implements an LLVM tool that's flag- and output-compatible
with macOS's `otool` -- except for bugs, but from testing with both
`otool` and `xcrun otool-classic`, llvm-otool matches vanilla
otool's behavior very well already. It's not 100% perfect, but
it's a very solid start.
This uses the same approach as llvm-objcopy: llvm-objdump uses
a different OptTable when it's invoked as llvm-otool. This
is possible thanks to D100433.

These are needed when buildling `clang-format` in a clean build dir.
It's a bit unfortunate that clang's lib/Basic depends on these
random TableGen targets. In the CMake build, this is less visible
because I think all llvm-tblgen's complete before all compiles there
(not sure though).
This is similar to D83530, but for llvm-objdump.
The motivation is the desire to add an `llvm-otool` symlink to
llvm-objdump that behaves like macOS's `otool`, using the same
technique the at llvm-objcopy uses to behave like `strip` (etc).
This change for the most part preserves behavior. In some cases,
it increases compatibility with GNU objdump a bit. For example,
the long options now require two dashes, and the long options
taking arguments for the most part now require a `=` in front
of the value. Exceptions are flags where tests passed the
value separately, for these the separate form is kept as
an alias to the = form.
The one-letter short form args are now joined or separate
and long longer accept a =, which also matches GNU objdump.
cl::opt<>s in libraries now have to be explicitly plumbed
through. This patch does that for --x86-asm-syntax=, but
there's hope that we can remove that again.
