Summary: This patch generalizes the existing code to support CDE intrinsics which will share some properties with existing MVE intrinsics (some of the intrinsics will be polymorphic and accept/return values of MVE vector types). Specifically the patch: * Adds new tablegen backends -gen-arm-cde-builtin-def, -gen-arm-cde-builtin-codegen, -gen-arm-cde-builtin-sema, -gen-arm-cde-builtin-aliases, -gen-arm-cde-builtin-header based on existing MVE backends. * Renames the '__clang_arm_mve_alias' attribute into '__clang_arm_builtin_alias' (it will be used with CDE intrinsics as well as MVE intrinsics) * Implements semantic checks for the coprocessor argument of the CDE intrinsics as well as the existing coprocessor intrinsics. * Adds one CDE intrinsic __arm_cx1 to test the above changes Reviewers: simon_tatham, MarkMurrayARM, ostannard, dmgreen Reviewed By: simon_tatham Subscribers: sdesmalen, mgorny, kristof.beyls, danielkiss, cfe-commits, llvm-commits Tags: #clang, #llvm Differential Revision: https://reviews.llvm.org/D75850
