x86 relocation is applied incorrectly to `0` in `%xmm0`

Relocs should not be applied to 0 in %xmm0.

Problematic regex / code:

        # Example %edi,0
        # Example movb $0x0,0x0
        if not addr_imm:
            addr_imm = re.search(r"(?:0x)?(?<![1-9])0$", args)

Just testing on regex101, adding \b to the beginning of the regex prevents capturing the 0 in %xmm0. https://regex101.com/r/UWEmrC/1
Not sure if this would cause any issues?

That's funny. Seems like a very safe fix to me.
