6bf55804 added special-case code for TY_PP_Fortran to
ToolChain::LookupTypeForExtension(), but
Darwin::LookupTypeForExtension() overrode that method without calling
the superclass implementation.
Make it call the superclass implementation to fix things.

D63607 made mac builders unhappy by failing this test, and it isn't
yet obvious why. Mark as unsupported as a temporary measure.

On Windows and macOS, the filesystem is case insensitive, and these files
interfere with each other. Reading through, the case of the file extension
is part of the test. I've altered the rest of the name instead.
This patch adds a new Flang mode. When in Flang mode, the driver will
invoke flang for fortran inputs instead of falling back to the GCC
toolchain as it would otherwise do.
The behaviour of other driver modes are left unmodified to preserve
backwards compatibility.
It is intended that a soon to be implemented binary in the flang project
will import libclangDriver and run the clang driver in the new flang
mode.
Please note that since the binary invoked by the driver is under
development, there will no doubt be further tweaks necessary in future
commits.
* Initial support is added for basic driver phases
* -E, -fsyntax-only, -emit-llvm -S, -emit-llvm, -S, (none specified)
* -### tests are added for all of the above
* This is more than is supported by f18 so far, which will emit errors
for those options which are unimplemented.
* A test is added that ensures that clang gives a reasonable error
message if flang is not available in the path (without -###).
* Test that the driver accepts multiple inputs in --driver-mode=flang.
* Test that a combination of C and Fortran inputs run both clang and
flang in --driver-mode=flang.
* clang/test/Driver/fortran.f95 is fixed to use the correct fortran
comment character.
