DSPJit: Replace/optimize LEAs
- LEA is a bit silly when the source and the destination are the same. A
simple ADD or SHL will do in those cases.
66 8D 04 45 00 00 00 00 lea ax,[rax*2]
66 03 C0 add ax,ax
48 8D 04 00 lea rax,[rax+rax]
48 03 C0 add rax,rax
66 8D 14 D5 00 00 00 00 lea dx,[rdx*8]
66 C1 E2 03 shl dx,3
- When scaling by 2, consider summing the register with itself instead.
The former always needs a 32-bit displacement, so the sum is more
compact.

66 8D 14 00 lea dx,[rax+rax]
