[Aarch64][SVE] Add intrinsics for gather loads (vector + imm)
This patch adds intrinsics for SVE gather loads from memory addresses generated by a vector base plus immediate index: * @llvm.aarch64.sve.ld1.gather.imm This intrinsics maps 1-1 to the corresponding SVE instruction (example for half-words): * ld1h { z0.d }, p0/z, [z0.d, #16] Committed on behalf of Andrzej Warzynski (andwar) Reviewers: sdesmalen, huntergr, kmclaughlin, eli.friedman, rengolin, rovka, dancgr, mgudim, efriedma Reviewed By: sdesmalen Tags: #llvm Differential Revision: https://reviews.llvm.org/D70806
