#5308: Generalize -msse2 command line flag to -msse<version number>

I'm looking into adding support for the `popcnt` instruction. The
instruction should be used if the user specifies `-msse4.2`*. I think we
should generalize the `-msse2` flag to be just `-msse` followed by a
version number.
* Although not formally part of the SSE 4.2 instruction set, the `popcnt`
instruction was added at the same time. GCC enables the `popcnt`
instruction if you specify `-msse4.2`, so I thought it'd be reasonable for
us to do so as well.
