instcombine: Migrate math library call simplifications This patch migrates the math library call simplifications from the simplify-libcalls pass into the instcombine library call simplifier. I have typically migrated just one simplifier at a time, but the math simplifiers are interdependent because: 1. CosOpt, PowOpt, and Exp2Opt all depend on UnaryDoubleFPOpt. 2. CosOpt, PowOpt, Exp2Opt, and UnaryDoubleFPOpt all depend on the option -enable-double-float-shrink. These two factors made migrating each of these simplifiers individually more of a pain than it would be worth. So, I migrated them all together. llvm-svn: 167815
