b9807cdcf1 Replace more uses of sse41 with sse4.1. 
llc using the host cpu features and *waning* on unknown features is probably
not a good thing :-(

5f6f8101d5 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:

2a0cce6b1c If unsafe FP optimization is not set, don't allow -(A-B) => B-A because 
when A==B, -0.0 != +0.0.
