Make the msse4/mno-sse4 flags aliases of the maximum sse values
...
they enable/disable.
This fixes two things:
a) sse4 isn't actually a target feature, don't treat it as one.
b) we weren't correctly disabling sse4.1 when we'd pass -mno-sse4
after enabling it, thus passing preprocessor directives and
(soon) passing the function attribute as well when we shouldn't.

Fix test.
...
With -### clang return 0, so we have to use FileCheck to see if there was an
error.

Ignore -mieee-fp.
...
It looks like clang always produce code with the ieee comparisons, so it is
safe to ignore this flag (we still error on -mno-ieee-fp).

Move the logic for selecting the last feature in the command line to the driver.
...
This is a partial revert of r188817 now that the driver handles -target-feature
in a single place.

Centralize the logic for handling -m* options and fix pr16943.
...
This moves the logic for handling -mfoo -mno-foo from the driver to -cc1. It
also changes -cc1 to apply the options in order, fixing pr16943.
The handling of -mno-mmx -msse is now an explicit special case.

Make clang behave in a gcc-compatible way in the presence of multiple flags for the same x86 target feature (e.g. -mno-sse -msse). gcc uses a somewhat unintuitive algorithm here in that the enabled SSE instructions is based on the order of the *last* flag for *each* feature-level, so that "-mno-sse -msse2" only enables SSE2, but "-mno-sse -msse2 -msse" enables all SSE levels.
