Sintendo 575f1b309a x64Emitter: short MOV for 64bit immediates (1)
Prior to this commit, the emitter would unconditionally emit a 10-byte
instruction known as MOVABS when loading a 64-bit immediate to a
register.

0:  48 b8 ef be ad de ff    movabs rax,0xffffffffdeadbeef
7:  ff ff ff

With this change, it will instead emit a 7-byte instruction when it is
possible to express the 64-bit immediate using a signed 32-bit value.

0:  48 c7 c0 ef be ad de    mov    rax,0xffffffffdeadbeef
