Mikhail Maltsev 7a85e3585e [ARM,CDE] Implement GPR CDE intrinsics
Summary:
This change implements ACLE CDE intrinsics that translate to
instructions working with general-purpose registers.

The specification is available at
https://static.docs.arm.com/101028/0010/ACLE_2019Q4_release-0010.pdf

Each ACLE intrinsic gets a corresponding LLVM IR intrinsic (because
they have distinct function prototypes). Dual-register operands are
represented as pairs of i32 values. Because of this the instruction
selection for these intrinsics cannot be represented as TableGen
patterns and requires custom C++ code.

Mikhail Maltsev 47edf5bafb [ARM,CDE] Generalize MVE intrinsics infrastructure to support CDE
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
