This patch add the ISD::LRINT and ISD::LLRINT 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 lrint/llrint generation for AArch64 in a subsequent patch. Current semantic is just route it to libm symbol.
