Michael Jones a200d6cdf0 [libc] make part of libc's unit test framework independent of llvm
This is mostly changing stringref to std::string, outs() to cout,
and small supporting changes. This will make running unit tests possible
on systems that are only grabbing the libc part of llvm.

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.
