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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@360889 91177308-0d34-0410-b5e6-96231b3b80d8
