std.Target.Cpu.Arch: Remove the aarch64_32 tag.
...
This is a misfeature that we inherited from LLVM:
* https://reviews.llvm.org/D61259
* https://reviews.llvm.org/D61939
(`aarch64_32` and `arm64_32` are equivalent.)
I truly have no idea why this triple passed review in LLVM. It is, to date, the
*only* tag in the architecture component that is not, in fact, an architecture.
In reality, it is just an ILP32 ABI for AArch64 (*not* AArch32).
The triples that use `aarch64_32` look like `aarch64_32-apple-watchos`. Yes,
that triple is exactly what you think; it has no ABI component. They really,
seriously did this.
Since only Apple could come up with silliness like this, it should come as no
surprise that no one else uses `aarch64_32`. Later on, a GNU ILP32 ABI for
AArch64 was developed, and support was added to LLVM:
* https://reviews.llvm.org/D94143
* https://reviews.llvm.org/D104931
Here, sanity seems to have prevailed, and a triple using this ABI looks like
`aarch64-linux-gnu_ilp32` as you would expect.
As can be seen from the diffs in this commit, there was plenty of confusion
throughout the Zig codebase about what exactly `aarch64_32` was. So let's just
remove it. In its place, we'll use `aarch64-watchos-ilp32`,
`aarch64-linux-gnuilp32`, and so on. We'll then translate these appropriately
when talking to LLVM. Hence, this commit adds the `ilp32` ABI tag (we already
have `gnuilp32`).

link.Coff: Basic support for /Brepro in the self-hosted linker.
...
Just keep things simple and zero the timestamp. It's not obvious that there's
any real benefit to adding complexity and harming performance by computing a
hash of the whole file for the timestamp value.
See:
* https://learn.microsoft.com/en-us/windows/win32/debug/pe-format#general-concepts
* https://learn.microsoft.com/en-us/windows/win32/debug/pe-format#debug-type
In the future, we should at least add an empty `IMAGE_DEBUG_TYPE_REPRO` entry to
the debug data directory for this case, but I didn't want to do too much surgery
right now since it's early days for COFF support in the self-hosted linker.

with this rewrite we can call functions inside of

all that's left is to implement lr/sc loops for atomically manipulating
1 and 2 byte values, after which we can use the segfault handler logic.
