%default {"result":"%eax"}
* Generic 32-bit "lit8" binary operation. Provide an "instr" line
* that specifies an instruction that performs "result = eax op ecx".
* This could be an x86 instruction or a function call. (If the result
* comes back in a register other than r0, you can override "result".)
* For: add-int/lit8, rsub-int/lit8
* and-int/lit8, or-int/lit8, xor-int/lit8,
* shl-int/lit8, shr-int/lit8, ushr-int/lit8
