  -----------
  [libc] Enable the 'stdlib' unit tests to be hermetic

This changes the `stdlib` tests to the new `add_libc_test` framework.
This applies to all but the exit tests.

  -----------
  [libc] Split out FPExceptMatcher from the FP utils

The FPEceptMatcher.cpp file uses system utilities and includes C++
libraries. This patch pulls it out of the main `FPTestHelpers` target so
we can exclude it from hermetic only tests.

  Log Message:
  -----------
  [libc] Enable the '__support' unit tests to be hermetic

This patch updates the `__support` unit tests to be built as hermetic
tests. The only tests we needed to disable were because of the use of
`realloc` which is not implemented correctly as it doesn't copy the
memory.

  Log Message:
  -----------
  [libc] Don't use '-nolibc' on the GPU build

We previously changed this to use `nolibc` to allow it to link in
compiler builtins for the CPU build. However, these options are unused
on the GPU and create a lot of noise. Furthermore, we want to use
`nogpulib` to prevent the linking in of the vendor libraries.
