x64Emitter: Short MOVs for 32bit immediates

Prior to this commit, the emitter would emit a 7-byte instruction when
loading a 32-bit immediate to a 64-bit register.

0:  48 c7 c0 ff ff ff 7f    mov    rax,0x7fffffff

With this change, it will check if it can instead emit a load to a
32-bit register, which takes only 5 or 6 bytes.

0:  b8 ff ff ff 7f          mov    eax,0x7fffffff
