/*
* Generic 32-bit binary operation. Provide an "instr" line that
* specifies an instruction that performs "result = eax op (rFP,%ecx,4)".
* This could be an x86 instruction or a function call. (If the result
* comes back in a register other than eax, you can override "result".)
*
* For: add-int, sub-int, and-int, or-int,
* xor-int, shl-int, shr-int, ushr-int
