KVM: x86: Move Src2Shift up one bit (use bits 36:32 for Src2 in the emulator)
An irresistible microoptimization (changing accesses to Src2 to just an
AND :)) that also frees a bit for AVX in the low flags word. This makes
it closer to SSE since both of them can access XMM registers, pointlessly
shaving another clock cycle or two (maybe).
No functional change intended.
