I for one would love to see this; I sometimes consider it to be a bit
of a misfeature that we support options exactly the way GCC does. In
my opinion, it might be nice to make the 'clang' driver have options
that we've worked out and then have a 'clang -gcc' driver for
compatibility, or something similar.
