Add an accelerated version of F_TO_I for x86_64
According to a quick micro-benchmark, this new version is 20% faster on my
Haswell laptop.
v2: Removed the XXX note about x86_64 from the comment
v3: Use an intrinsic instead of an __asm__ block. This should give us MSVC
support for free.
v4: Enable it for all x86_64 builds, not just with USE_X86_64_ASM
