Vixl has migrated its upstream repo to https://gitlab.arm.com/runtimes/vixl
without telling anyone. Rebase on their current main rather than the
dead project.
At the very least removes the obnoxious `operator""_h` warnings. Not too
much has changed since our last rebased.
Fixes#5237
ankerl::unordered_dense is faster on average and has less memory usage
than tsl::robin_map. It is pretty significantly faster than std but
we'll keep that as is for now.
Obviously, this will need a lot of testing.

Integrate Zydis as an optional dependency to enable x86/x86-64 guest
instruction disassembly during JIT compilation.
Build with -DENABLE_ZYDIS=TRUE.
Use FEX_X86DISASSEMBLE=1 at runtime to output guest x86 instructions
for each compiled block.
- Do compiler/architecture checks EARLY, don't waste time doing random
configuration stuff if the user can't even compile in the first place
- MSVC is unsupported, I assume? So add a check to disallow. There's
literally no MSVC or MSC_VER checks anywhere, so...
- Rather than using the MSVC architecture definitions, use our own
`ARCHITECTURE_arm64` et al. Hijacking existing "standard" definitions
is a very bad idea. Also makes it more readable in CMake
- Change the x86 host check to `x86|amd64`. Some systems still refer to
themselves as x86 despite being 64-bit for... reasons, and I saw one a
very long time ago that referred to it as amd64. This should
basically never come up, nor is it really relevant given that FEX is
for arm64... but it kinda annoyed me so whatever.
TODOs:
- Should we check `CMAKE_SIZEOF_VOID_P (equal) 64`? I don't think anyone
is even trying to compile this thing on armv7 or older, but might as
well? maybe?
- What's the status of *BSD, Solaris, macOS? Technically macOS does
support Wine, not sure about the others.

Trivial variables like SRCS, NAME, etc. actually do more harm than good.
They *will* make your IDE mad, and are also less readable. Remember:
verbosity is not a bad thing! Usually
Also: did a few tiny cleanups that I missed from my `endpara` PR.

- Some CMake LSPs have aneurysms when you put the end parenthesis on a
different line. Annoying? Yes, but this is all we can really do about
it for now.
- `set`, `option`, and `message` should not have spaces before their
opening parenthesis.

This reverts commit e1a45a2720, reversing
changes made to bd7edd8651.
The change rendered pressure-vessel non-functional on muvm-based setups
like Fedora Asahi Remix.
Ignore any additional jemalloc configuration options, can come from
`/etc/malloc.conf` or even the `MALLOC_CONF` environment variable.
Ensure nothing can override our options.
And also use it at the same time, since the function signatures changed.
Instead of relying on the host libc math libraries for `long double` ALU
operations, rewrite the entire thing to use softfloat-3e fixed width
float128_t types.
This is a very invasive change in cephes but is a necessary requirement
for getting the precision we require in environments that map `long
double` to be the same as `double`, like Win32 and MacOS.
This fixes the precision issue in transcendental operations when running
under WINE.
