[libc] Reduce direct use of errno in src/stdlib and src/__support tests.

 [libc] Move libc_errno inside of LIBC_NAMESPACE (#80774) 2024-02-06T09:36:05+00:00 michaelrj-google 71531609+michaelrj-google@users.noreply.github.com 2024-02-06T09:36:05+00:00 3eb1e6d8e930f5aff17b8d6bcc160f5bbf8cabc7 Having libc_errno outside of the namespace causes versioning issues when trying to link the tests against LLVM-libc. Most of this patch is just moving libc_errno inside the namespace in tests. This isn't necessary in the function implementations since those are already inside the namespace.

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

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] Add strtoint32 and strtoint64 tests

There were regressions in the testing framework due to none of the
functioning buildbots having a 32 bit long. This allowed the 32 bit
version of the strtointeger function to go untested. This patch adds
tests for strtoint32 and strtoint64, which are internal testing
functions that use constant integer sizes. It also fixes the tests to
properly handle these situations.

[libc] Make ErrnoSetterMatcher handle logging floating point values.

Along the way, couple of additional things have been done:

1. Move `ErrnoSetterMatcher.h` to `test/UnitTest` as all other matchers live
   there now.
2. `ErrnoSetterMatcher` ignores matching `errno` on GPUs.

[libc] Use MPFR for strtofloat fuzzing

The previous string to float tests didn't check correctness, but due to
the atof differential test proving unreliable the strtofloat fuzz test
has been changed to use MPFR for correctness checking. Some minor bugs
have been found and fixed as well.
