Joseph Huber f4002c1415 [libc] Enable running libc unit tests on NVPTX 
The previous patches added the necessary support for global constructors
used to register tests. This patch enables the NVPTX target to build
and run the unit tests on the GPU. Currently this only tests the ctype
tests, but adding more should be straightforward from here on.

This ran all the ctest unit tests when run on an sm_70.

Depends on D149517 D149527

The LLVM libc unit test framework

This directory contains a lightweight implementation of a gtest like unit test framework for LLVM libc.

Why not gtest?

While gtest is great, featureful and time tested, it uses the C and C++ standard libraries. Hence, using it to test LLVM libc (which is also an implementation of the C standard libraries) causes various kinds of mixup/conflict problems.

How is it different from gtest?

LLVM libc's unit test framework is much less featureful as compared to gtest. But, what is available strives to be exactly like gtest.

Will it be made as featureful as gtest in future?

It is not clear if LLVM libc needs/will need every feature of gtest. We only intend to extend it on an as needed basis. Hence, it might never be as featureful as gtest.
