[ARM] MVE VCVT lowering for f32->f16 truncs
This adds code to lower f32 to f16 fp_trunc's using a pair of MVE VCVT instructions. Due to v4f16 not being legal, fp_round are often split up fairly early. So this reconstructs the vcvt's from a buildvector of fp_rounds from two vector inputs. Something like: BUILDVECTOR(FP_ROUND(EXTRACT_ELT(X, 0), FP_ROUND(EXTRACT_ELT(Y, 0), FP_ROUND(EXTRACT_ELT(X, 1), FP_ROUND(EXTRACT_ELT(Y, 1), ...) It adds a VCVTN node to handle this, which like VMOVN or VQMOVN lowers into the top/bottom lanes of an MVE instruction. Differential Revision: https://reviews.llvm.org/D81139
