Oops, I wasn't done with that last comment.

Anyway, while I'm looking at the testsuite framework mechanism, perhaps someone
can determine which options are appropriate to run for various x86 targets and
come up with tests to determine whether a particular instruction set is supported
on the test hardware so we'll know whether the test should be "run" or "compile"
for that set.  I'm thinking of something like check_x86_vect_hw_available that
takes as argument -mmmx/-msse/-msse2/-msse3/-m3dnow.  There might also be a
check_* proc that takes those arguments and says whether the option is supported
at all for this target (e.g., does x86_64 accept them all?).
