Chris Lattner f031e8ad01 Teach codegen to lower llvm.powi to an efficient (but not optimal) ...

multiply sequence when the power is a constant integer.  Before, our
codegen for std::pow(.., int) always turned into a libcall, which was
really inefficient.

This should also make many gfortran programs happier I'd imagine.
