While working on #66, I discovered that pext#/pdep# only use hardware instructions when enabling the -mbmi2 flag. This makes selectBits up to 20x faster! This is an x86-specific flag though and it's not available everywhere, so it shouldn't be enabled by default.

I realized, we can just make the future SIMD implementation use BMI2, since that's enabled by default anyway.
