Apparently I completely missed that cpuid, xgetbv, syscall,
l{u,}{div,rem} were failing to hit their optimized cases for inlining
and avoiding 128-bit software divide.
The divisions are a clear performance regression for 64-bit applications
since that is the only real way to do a 64-bit division on x86, I added
those specifically because it sped up games.
CPUID depends heavily on the game, since some games use that as a
serialization instruction fairly heavily.
XGETBV is trivial since it matches behaviour of CPUID (and is basically
an extension of it).
Syscall inlining can save a decent amount of time, again heavily depends
on game.
Adds multi-inst tests for all of these situations so that once it gets
fixed (Apparently broken once RCLSE got stripped out), we can see that
they keep working. Obviously tests couldn't have existed in instcountCI
before since we didn't support multi-instruction tests.
