Reapply a subset of r167567 to clean up Darwin-specific code for invoking gcc.
...
Unlike my previous attempt at this, this patch leaves intact the check for
whether clang can handle the input file type, and for non-Darwin toolchains it
will invoke gcc for things it cannot handle. For Darwin toolchains, the
behavior reported in pr14338 still occurs with this patch, but that is a
definite improvement from what happens currently, where it just crashes with
an assertion failure.
