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.

Linux-only for now. Some mac bits stubbed out, but not tested.
Good enough for the tiny_race.c example at
https://clang.llvm.org/docs/ThreadSanitizer.html :
$ out/gn/bin/clang -fsanitize=address -g -O1 tiny_race.c
$ while true; do ./a.out || echo $? ; done
While here, also make `-fsanitize=address` work for .c files.

This reverts commit 13aff21f0d,
since the CMake part relanded in c06a8f9caa.
The GN part is a bit simpler than last time due to the
prior simplifications in acea470c16.
RVV intrinsics has new overloading rule, please see
82aac7dad4
Changed:
1. Rename `generic` to `overloaded` because the new rule is not using C11 generic.
2. Change HasGeneric to HasNoMaskedOverloaded because all masked operations
support overloading api.
3. Add more overloaded tests due to overloading rule changed.
