[libc][Docs] Update the GPU RPC documentation (#79069)

this is intelligable and provides some useful examples.

[libc][NFC] Remove `FPBits` cast operator (#79142)

2024-01-23T16:30:19+00:00

The semantics for casting can range from "bitcast" (same representation)
to "different representation", to "type promotion". Here we remove the
cast operator and force usage of `get_val` as the only function to get
the floating point value, making the intent clearer and more consistent.

[libc][NFC] use builder pattern for ErrnoSetterMatcher (#79153)

2024-01-23T15:43:24+00:00

ErrnoSetterMatcher::returns can be misleading as it does not initialize
the errno. This is made worse as later on there is a switch statement on
the errno comparator using __builtin_unreachable(). This patch make
ErrnoSetterMatcher::returns give back a builder that is nomially
different from ErrnoSetterMatcher.
