PTAL.

Some addq/subq are kept when they are used to manipulate 64-bit value or
calculate the index register (might be negative) in the SIB mode.

src/x64/assembler-x64.h:1658: arithmetic_op_32(0x03, dst, src);
The arithmetic_op and arithmetic_op_32 could be unified to arithmetic_op(byte
opcode, Register reg, Register rm_reg, int size) to make the codes smaller. I
leave it to a future CL when all the arithmetic instructions have an
instruction##p version for x32. The current full list is at
https://github.com/fenghaitao/v8/blob/x32/tools/generate-x32-sources.py#L110.

Sounds good.
