Implement "visitPow". This is mainly used to see if we have a pow() call of this
...
form:
powf(10.0f, x);
If this is the case, and also we want limited precision floating-point
calculations, then lower to do the limited-precision stuff.

Create HandlePHINodesInSuccessorBlocksFast, a version of

HandlePHINodesInSuccessorBlocks that works FastISel-style. This
allows PHI nodes to be updated correctly while using FastISel.
This also involves some code reorganization; ValueMap and
MBBMap are now members of the FastISel class, so they needn't
be passed around explicitly anymore. Also, SelectInstructions
is changed to SelectInstruction, and only does one instruction
at a time.
