miyuki added a parent revision: D75843: [ARM,CDE] Implement CDE feature test macros.

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
