127487aa4d [libc] Add a new target named LibcHermeticTestMain.
The existing LibcTestMain has been renamed to LibcUnitTestMain.
Hermetic tests are linked to LibcHermeticTestMain and unit tests are
linked to LibcUnitTestMain.

5c9629a714 [libc][fix] Also remove the headers for the other flags
Summary:
This patch makes this only apply to the GPU build. This should be
handled more intelligently in the future so it's common between all of t
hem.

cb1facf48c [libc][fix] Only add the hermetic test flags in GPU mode
Summary:
This is a little broken, what we really need is a separate target to use
with the hermetic tests, but this is a stop-gap to get the bots green
again.

fb5a3bc8f8 [libc] Add path to include generated headers for hermetic tests
The generated header files live in the build directory's include path.
When targeting a hermetic build we want to make sure we only use headers
generated by the project itself if availible.

d94fe97280 [libc][bazel] add file printf targets and support
This patch adds targets for printf and fprintf to the bazel build.
Additionally, it adds support for the build system to specify where
files should be written for testing purposes. This was necessary to
enable the fprintf test under bazel.

1e8960c7a5 [libc] Add rule named add_libc_hermetic_test which adds a hermetic test.
A convenience wrapper name `add_libc_test` is also added which adds both
a unit test and a hermetic test. The ctype tests have been switched over
to use add_libc_test.

4e298c32d5 [libc] Make string tests compatible with the Fuchsia build
Some test code was doing loose conversions caught by compiler
warnings in  the Fuchsia build.  This included duplicated code
in a few tests that was reconsolidated with the existing header
file copy of the same functions.

The MemoryMatcher abstraction presumes gtest-style matcher support,
which is not available in Fuchsia's zxtest library.  It's avoided
in favor of simpler memory-comparing assertions.

af1315c28f [libc][NFC] Move UnitTest and IntegrationTest to the 'test' directory.
This part of the effort to make all test related pieces into the `test`
directory. This helps is excluding test related pieces in a straight
forward manner if LLVM_INCLUDE_TESTS is OFF. Future patches will also move
the MPFR wrapper and testutils into the 'test' directory.
