  Changed paths:
    M clang/lib/Driver/ToolChains/BareMetal.cpp
    M clang/test/Driver/baremetal.cpp

  Log Message:
  [clang] Allow using BareMetal toolchain with LLVM_ENABLE_PER_TARGET_RUNTIME_DIR compiler-rt

If you build compiler-rt with LLVM_ENABLE_PER_TARGET_RUNTIME_DIR then
the library filename will be "libclang_rt.builtins.a" instead of

The ToolChain::getCompilerRT method uses the "libclang_rt.builtins.a"
name if it can find the file in the library directories. If it can't
then it falls back to using "libclang_rt.builtins-<ARCH>.a". This
change adds the library directory such that "libclang_rt.builtins.a"
can be found.
