Use clang driver on MinGW where clang-cl is not usable. MSVC target
still uses clang-cl to minimize changes to existing test runners.

MinGW is GCC-like and does not support clang-cl, so clean up the lit cfg
to reflect that. Also mark all Windows test cases using clang-cl as
UNSUPPORTED for now. We should probably adapt most of these test cases
to use the GCC-like clang driver, but that will be for later.

This reverts commit 99796d06dbe11c8f81376ad1d42e7f17d2eff6ae.
Hint: Looking here because your manual invocation of something in
'check-asan' broke? You need a new symbolizer (after D123538).
An upcoming patch will remove the internal metadata for global
variables. With D123534 and D123538, clang now emits DWARF debug info
for constant strings (the only global variable type it was missing), and
llvm-symbolizer is now able to symbolize all global variable addresses
(where previously it wouldn't give you the file:line information).
Move ASan's runtime over from the internal metadata to DWARF.
