[libc][math][c23] Add rsqrtf() function (#159615)

2025-10-09T03:37:01+00:00

Closes #159614

**Changes:**
- Initial implementation of rsqrt for single precision float

**Some small unrelated style changes to this PR (that I missed in my
rsqrtf16 PR):**
- Added extra - to the top comments to make it look nicer in
libc/shared/math/rsqrtf16.h
- Put rsqrtf16 inside of libc/src/__support/math/CMakeLists.txt in
sorted order
- Rearanged libc_math_function rsqrtf16 in Bazel to match alphabetical
order

[libc] fix error: implicit conversion loses floating-point precision: 'double' to 'float' in shared_math_test.cpp (#159934)

2025-09-20T17:07:40+00:00

This test fails under `-Werror=implicit-float-conversion` (like in our
pre-merge CI) because `dsqrtl` returns a double
