Use lit's internal shell when running tests on Windows

The internal shell is faster and more predictable than any copy of
bash.exe on the user's system.

LLVM and Clang use the internal shell by default, and have an
environment variable to disable it. I don't think compiler-rt needs that
complexity, so I left it out.
