27cfff8f44 x86_64: pass exact integer bit sizes to compiler-rt routines 
This was a hack around compiler-rt not computing the correct size.

test: Disable a bunch of vector behavior tests for hexagon. 
Most of the failures are:

* https://github.com/llvm/llvm-project/issues/118879
* https://github.com/llvm/llvm-project/issues/134659

But some are also miscompilations leading to wrong results. I'm not going to
investigate the latter further until all the backend crashes have been resolved.

musl: Add hexagon-linux-musl sources. 
This is from Qualcomm's fork: https://github.com/quic/musl

I maintain a fork of musl where I rebase Qualcomm's changes on top of the latest
musl release, which I then use as the basis for musl updates in Zig. My fork can

4b63f94b4e Fix sigaddset/sigdelset bit-fiddling math 
The code was using u32 and usize interchangably, which doesn't work on
64-bit systems.  This:
  `pub const sigset_t = [1024 / 32]u32;`
is not consistent with this:
  `const shift = @as(u5, @intCast(s & (usize_bits - 1)));`

However, normal signal numbers are less than 31, so the bad math doesn't matter much.  Also, despite support for 1024 signals in the set, only setting signals between 1 and NSIG (which is mostly 65, but sometimes 128) is defined.  The existing tests only exercised signal numbers in the first 31 bits so they didn't trip over this:

The C library `sigaddset` will return `EINVAL` if given an out of bounds signal number.  I made the Zig code just silently ignore any out of bounds signal numbers.

Moved all the `sigset` related declarations next to each in the source, too.

The `filled_sigset` seems non-standard to me.  I think it is meant to be used like `empty_sigset`, but it only contains 31 set signals, which seems wrong (should be 64 or 128, aka `NSIG`).  It's also unused.  The oddly named but similar `all_mask` is used (by posix.zig) but sets all 1024 bits (which I understood to be undefined behavior but seems to work just fine).  For comparison the musl `sigfillset` fills in 65 bits or 128 bits.

991560fb49 linux.zig: epoll_wait: pass kernel sigset size 
Linux kernel syscalls expect to be given the number of bits of sigset that
they're built for, not the full 1024-bit sigsets that glibc supports.

I audited the other syscalls in here that use `sigset_t` and they're all
using `NSIG / 8`.

Fixes #12715

4fc783670a Sema/arith.zig: Fixing more typos from #23177. 
This is a complementary PR to #23487 (I had only found one typo before).

Now I've looked at the whole `arith.zig` file, trying to find other potential problems.

Make translate-c more robust in handling macro functions. 
Translate-c didn't properly account for C macro functions having parameter names that are C keywords. So something like `#define FOO(float) ((float) + 10)` would've been interpreted as casting `+10` to a `float` type, instead of adding `10` to the parameter `float`.

An example of a real-world macro function like this is SDL3's `SDL_DEFINE_AUDIO_FORMAT` from `SDL_audio.h`, which uses `signed` as a parameter.
