[lit][tests]Add feature libcxx-used and use it in llvm-*-fuzzer tests

Authored by xingxue on Apr 29 2019, 8:40 AM.



When a LLVM binary such as llvm-*-fuzzer is built with libc++, it has dependency on libc++. The path to find shared libraries specified in llvm-*-fuzzer is relative. As a result, these binaries cannot be copied to an arbitrary directory and launched from there. Changes in this patch add a LIT feature to indicate that libc++ is used to build and, based on the feature exclude test cases that test by copying llvm-*-fuzzer binaries to a directory.

The changes in this patch use macro LLVM_LIBCXX_USED introduced in patch D61016 should be committed before this patch.
