AVX2: Verify O/S support for AVX2 before enabling
This fixes crashes that would occur when attempting to use
libjpeg-turbo's AVX2 extensions on older O/S's (such as Windows XP or
RHEL 5.) Even if the CPU supports AVX2, the O/S has to also support
saving/restoring YMM registers when switching contexts.

Clean up SIMD glue code
The SIMD glue code has gotten a bit #ifdef heavy so clean it up by having
one file for each possible SIMD arch. This also allows a simplification of
the x86_64 code as SSE/SSE2 is always known to exist on that arch.
