Jit64: divwx - Eliminate MOV for division by power of 2
Division by a power of two can be slightly improved when the
destination and dividend registers are the same.
Before:
8B C6 mov eax,esi
85 C0 test eax,eax
8D 70 03 lea esi,[rax+3]
0F 49 F0 cmovns esi,eax
C1 FE 02 sar esi,2
After:
85 F6 test esi,esi
8D 46 03 lea eax,[rsi+3]
0F 48 F0 cmovs esi,eax
C1 FE 02 sar esi,2
