part of PR4405: disable a contentious optimization for
...
strcmp -> memcmp when the lengths of the strings are unknown.

Split the Add, Sub, and Mul instruction opcodes into separate
...
integer and floating-point opcodes, introducing
FAdd, FSub, and FMul.
For now, the AsmParser, BitcodeReader, and IRBuilder all preserve
backwards compatability, and the Core LLVM APIs preserve backwards
compatibility for IR producers. Most front-ends won't need to change
immediately.
This implements the first step of the plan outlined here:
