`long double` is haunted on most architectures, but it is especially so on i386-linux-gnu. While have 80b of significant data, on i386-linux-gnu this type has 96b of storage. Fixes for supporting printf family of conversions for `long double` on i386-linux-gnu. This allows the libc-stdlib-tests and libc_stdio_unittests ninja target tests to pass on i386-linux-gnu.

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.
