libzigc/math: Implement rintl, lrintl (#31791 )
...
It's a fairly straightforward port of `musl`'s `rintl`, like `rint` and `rintf` were. `libc-test` tests for `rintl` are uncommented since they're now passing.
I've also covered special cases for `rint` with tests, and broke down the current `rint` and `modf` test declarations into multiple -- so each libc function get its own test declaration at the very least.

std.math.big.int: address log2/log10 reviews

There were good reviews made after #31365 was merged, so this commit
addresses them separately.
1. Assert that the number is greater than zero
2. Use `constants` instead of calculating constants manually
3. Use `Const.bitCountAbs` for log2

zig libc: acosf: fix fp exceptions
...
some fp exceptions are prohibited by zig test-libc (libc-test).
Promoting to f64 prevents vectorization of some floating point
divisions. The vectorization has unused lanes which contain zero. On
division the lanes containing zero are divided and trigger the INVALID
fp flags.

libzigc: hypot ( #31104 )
...
First time contribution.
Implements hypot for libzigc #30978 .
Commands i run:
```
$ stage3/bin/zig build -p stage4 -Denable-llvm -Dno-lib
$ stage4/bin/zig build test-libc -Dlibc-test-path=../../libc-test -Dtest-filter=hypot --summary line -fqemu -fwasmtime
Build Summary: 725/737 steps succeeded (12 skipped)
```
I also changed std.math.hypot becuase some libc-tests raised fp exceptions. Example:
```
../../libc-test/src/math/special/hypot.h:8: bad fp exception: RN hypot(0x1p-1074,0x0p+0)=0x1p-1074, want 0 got INEXACT|UNDERFLOW
../../libc-test/src/math/special/hypot.h:9: bad fp exception: RN hypot(0x1p-1074,-0x0p+0)=0x1p-1074, want 0 got INEXACT|UNDERFLOW
```
I also run this command as a quick sanity check:
```
$ stage4/bin/zig build test-std -Dtest-filter=hypot -Dtest-target-filter=x86_64-linux-musl --summary line
Build Summary: 5/5 steps succeeded; 136/136 tests passed
```

The software impl of `acos` and `asin` depends on the `sqrt` op. Since support for `sqrt` in `f16`, `f80`, and `f128` has been added, the impl of `acos` and `asin` for `f16`, `f80`, and `f128` is now being supplemented.

represent Mac Catalyst as aarch64-maccatalyst-none rather than aarch64-ios-macabi
...
Apple's own headers and tbd files prefer to think of Mac Catalyst as a distinct
OS target. Earlier, when DriverKit support was added to LLVM, it was represented
a distinct OS. So why Apple decided to only represent Mac Catalyst as an ABI in
the target triple is beyond me. But this isn't the first time they've ignored
established target triple norms (see: armv7k and aarch64_32) and it probably
won't be the last.
While doing this, I also audited all Darwin OS prongs throughout the codebase
and made sure they cover all the tags.
