Jit64: slwx - Handle constant zero input
Shifting zero by any amount always gives zero.
Before:
41 BF 00 00 00 00 mov r15d,0
8B CF mov ecx,edi
49 D3 E7 shl r15,cl
45 8B FF mov r15d,r15d
After:
Nothing, register is set to constant zero.
All games I've tried hit this optimization on launch. In Soul Calibur II
it occurs very frequently during gameplay.
