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. llvm-svn: 92388

Mass update to CodeGen tests to use CHECK-LABEL for labels corresponding to function definitions for more informative error messages. No functionality change and all updated tests passed locally.

; CHECK: fldt 4(%esp)
[X86] Print %st(0) as %st to match what gcc inline asm uses as the clobber name to make MS inline asm work correctly Summary: When calculating clobbers for MS style inline assembly we fail if the asm clobbers stack top because we print st(0) and try to pass it through the gcc register name check. This was found with when I attempted to make a emms/femms clobber all ST registers. If you use emms/femms in MS inline asm we would try to use st(0) as the clobber name but clang would think that wasn't a valid clobber name. This also matches what objdump disassembly prints. It's also what is printed by gcc -S.

Have the X86 back-end emit the alias instead of what's being aliased. In most cases, it's much nicer and more informative reading the alias. llvm-svn: 129497
