708894cf99 add a debug subcommand for printing LLVM integer type alignment 
Useful when debugging why upgrading from LLVM 17 to 18 caused C ABI
regressions. Turns out LLVM 18 does the following insane thing:

6730b366a0 LLVM backend: no more signext on aarch64 
Clang doesn't do it, so Zig must not do it in order to match the C ABI.

6986d2aca9 x86_64 sysv C ABI: fix f128 param and return types 
Clang 17 passed struct{f128} parameters using rdi and rax, while Clang
18 matches GCC 13.2 behavior, passing them using xmm0.

This commit makes Zig's LLVM backend match Clang 18 and GCC 13.2. The
commit deletes a hack in x86_64/abi.zig which miscategorized f128 as
"memory" which obviously disagreed with the spec.

200e06b239 update maxIntAlignment for x86 to 16 
LLVMABIAlignmentOfType(i128) reports 16 on this target, however the C
ABI uses align(4).

Clang in LLVM 17 does this:

%struct.foo = type { i32, i128 }

Clang in LLVM 18 does this:

%struct.foo = type <{ i32, i128 }>

Clang is working around the 16-byte alignment to use align(4) for the C
ABI by making the LLVM struct packed.

06ee65af9e libcxx: update to LLVM 18 
release/18.x branch, commit 78b99c73ee4b96fe9ce0e294d4632326afb2db42

This adds the flag `-D_LIBCPP_HARDENING_MODE` which is determined based
on the Zig optimization mode.

This commit also fixes libunwind, libcxx, and libcxxabi to properly
report sub compilation errors.

65bea9ac07 LLVM 18 update: avoid passing vectors sometimes

* some manual fixes to generated CPU features code. In the future it

* add to various target OS switches. Some of the values I was unsure of
  and added TODO panics, for example in the case of spirv CPU arch.
