Matt Arsenault 6b00d40900 InstCombine: Check source value precision when reducing cast intrinsic 
Missed this check when porting from the libcall version.

Matt Arsenault 7233344c28 SimplifyLibCalls: Replace fabs libcalls with intrinsics 
Add missing fabs(fpext) optimzation that worked with the call,
and also fixes it creating a second fpext when there were multiple
uses.

Meador Inge 193e035b9c 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.
