fix a subtle bug I introduced in my refactoring, where we stopped preferring
the i8 versions of instructions in some cases. In test6, we started
generating:
cmpq $0, -8(%rsp) ## encoding: [0x48,0x81,0x7c,0x24,0xf8,0x00,0x00,0x00,0x00]
## <MCInst #478 CMP64mi32
## <MCOperand Reg:114>
## <MCOperand Imm:1>
## <MCOperand Reg:0>
## <MCOperand Imm:-8>
## <MCOperand Reg:0>
## <MCOperand Imm:0>>
instead of:
cmpq $0, -8(%rsp) ## encoding: [0x48,0x83,0x7c,0x24,0xf8,0x00]
## <MCInst #479 CMP64mi8
## <MCOperand Reg:114>
## <MCOperand Imm:1>
## <MCOperand Reg:0>
## <MCOperand Imm:-8>
## <MCOperand Reg:0>
## <MCOperand Imm:0>>
Fix this and add some comments.
