Error messages never contain periods or grave accents.
Get rid of the periods and use apostrophes instead in
probably the only two error messages that had them.
Most of these are gated by -Dtest-extra-targets because:
* We don't really have CI resources to spare at the moment.
* They're relatively niche if you're not on a musl distro.
* And the few musl distros that exist don't support all these targets.
* Quite a few of them are broken and need investigating.
x86_64-linux-musl and aarch64-linux-musl are not gated as they're the most
common targets that people will be running dynamic musl on, so we'll want to
have some bare minimum coverage of those.
* When storing a zero-bit type, we should short-circuit almost
immediately. Zero-bit stores do not need to do any work.
* The bit size computation for arrays is incorrect; the `abiSize` will
already be appropriately aligned, but the logic to do so here
incorrectly assumes that zero-bit types have an alignment of 0. They
don't; their alignment is 1.

I changed to `wasm/abi.zig`, this design is certainly better than the previous one. Still there is some conflict of interest between llvm and self-hosted backend, better design will appear when abi tests will be tested with self-hosted.

By returning an initialized sigset (instead of taking the set as an output
parameter), these functions can be used to directly initialize the `mask`
parameter of a `Sigaction` instance.
When linking a libc, Zig should defer to the C library for sigset
operations. The pre-filled constants signal sets (empty_sigset,
filled_sigset) are not compatible with C library initialization, so remove
them and use the runtime `sigemptyset` and `sigfillset` methods to
initialize any sigset.
* Indexing zero-bit types should not produce AIR indexing instructions
* Getting a runtime-known element pointer from a many-pointer should
check that the many-pointer is not comptime-only

The last Intel Quark MCU was released in 2015. Quark was announced to be EOL in
2019, and stopped shipping entirely in 2022.
The OS tag was only meaningful for Intel's weird fork of Linux 3.8.7 with a
special ABI that differs from the regular i386 System V ABI; beyond that, the
CPU itself is just a plain old P54C (i586). We of course keep support for the
CPU itself, just not Intel's Linux fork.
