dd4be26f53 libc-test: disable daemon-failure.c 
It's flaky in that systems with a high FD limit will get an unexpected ENOMEM
error from daemon(), failing the test.

7f49dae284 Fix PowerPC restore_rt 
Clang fails to compile the CBE translation of this code ("non-ASM
statement in naked function"). Similar to the implementations of
`restore_rt` on x86 and ARM, when the CBE is in use, this commit employs
alternative inline assembly that avoids using non-immediate input
operands.

std: always allow spawning processes when an env map is explicitly provided (#25092) 
In a library, the two `builtin.link_libc` and `builtin.output_mode ==
.Exe` checks could both be false. Thus, you would get a compile error
even if you specified an `env_map` at runtime. This change turns the
compile error into a runtime panic and updates the documentation to
reflect the runtime requirement.

bdca0f93c4 Fix PowerPC syscalls causing invalid code from CBE 
Fixes #25209.

On PowerPC, some registers are both inputs to syscalls and clobbered by
them. An example is r0, which initially contains the syscall number, but
may be overwritten during execution of the syscall.

musl and glibc use a `+` (read-write) constraint to indicate this, which
isn't supported in Zig. The current implementation of PowerPC syscalls
in the Zig standard library instead lists these registers as both inputs
and clobbers, but this results in the C backend generating code that is
invalid for at least some C compilers, like GCC, which doesn't support
the specifying the same register as both an input and a clobber.

This PR changes the PowerPC syscall functions to list such registers as
inputs and outputs rather than inputs and clobbers. Thanks to jacobly0
who pointed out that it's possible to have multiple outputs; I had
gotten the wrong idea from the documentation.

std.pie: fix register constraint in getDynamicSymbol() for s390x (#25327) 
If the compiler happens to pick `ret = r0`, then this will assemble to
`ag r0, 0` which is obviously not what we want. Using `a` instead of `r` will
ensure that we get an appropriate address register, i.e. `r1` through `r15`.

Re-enable pie_linux for s390x-linux which was disabled in
ed7ff0b693037078f451a7c6c1124611060f4892.

2a97e0af6d CI: stop testing x86_64-macos 
There are two reasons for this:

1. Apple is about to drop support for this target. Zig will keep support
   but move it to a lower tier - one that does not require continuous CI
   testing. Support for this target will be maintained by the enthusiasm
   of contributors but will not block other bug fixes and enhancements.
2. This is our only non-self-hosted action runner. We are migrating away
   from GitHub soon at which point this runner will no longer be
   available.
