integer and floating-point opcodes, introducing
FAdd, FSub, and FMul.
For now, the AsmParser, BitcodeReader, and IRBuilder all preserve

compatibility for IR producers. Most front-ends won't need to change
immediately.
This implements the first step of the plan outlined here:

id could end up being wrong mostly because of
forgetting to remap new nodes that morphed into
processed nodes through CSE.
