Sintendo dfb32040bf Jit64: divwx - Micro-optimize division by 2
Prefer using eax to isolate the sign bit. This saves a byte when the
destination ends up as r8-15, because those require a REX prefix.

Before:
41 8B C5             mov         eax,r13d
41 C1 ED 1F          shr         r13d,1Fh
44 03 E8             add         r13d,eax
41 D1 FD             sar         r13d,1

After:
41 8B C5             mov         eax,r13d
C1 E8 1F             shr         eax,1Fh
44 03 E8             add         r13d,eax
41 D1 FD             sar         r13d,1
