This patch add the ISD::LROUND and ISD::LLROUND along with new intrinsics. The changes are straightforward as for other floating-point rounding functions, with just some adjustments required to handle the return value being an interger. The idea is to optimize lround/llround generation for AArch64 in a subsequent patch. Current semantic is just route it to libm symbol. llvm-svn: 360889
