Bug Description

Already present in Sandy Bridge.
AMD promises to support the same in Bulldozer.
I know that there is cl-simd, but I plan to investigate this from scratch.
Ideally, SBCL should figure out whether CPU has AVX or not, and turn the corresponding support in the compiler on/off.

This shouldn't be limited to AVX. SBCL doesn't use even more common extensions, like SSE2 on x86 (although it does for x86_64). So what needs to be done is some general way to specialize architecture more finely, like -march for GCC
