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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92388 91177308-0d34-0410-b5e6-96231b3b80d8
