aarch64: Refactor AdvSIMD intrinsics

Refactor AdvSIMD intrinsics defined using the new pragma-based approach
so that it is more extensible.

Introduce a new struct, simd_type, which defines types using a mode and
qualifiers, and use objects of this struct in the declaration of intrinsics
in the aarch64-simd-pragma-builtins.def file.

Change aarch64_pragma_builtins_data struct to support return type and
argument types.

Refactor aarch64_fntype and aarch64_expand_pragma_builtin so that it
initialises corresponding vectors in a loop. As we add intrinsics with
more arguments, these functions won't need to change to support those.

gcc/ChangeLog:

	* config/aarch64/aarch64-builtins.cc
	(ENTRY): Modify to add support of return and argument types.
	(struct simd_type): New struct to declare types using mode and
	qualifiers.
	(struct aarch64_pragma_builtins_data): Replace mode with
	the array of types to support return and argument types.
	(aarch64_fntype): Modify to handle different signatures.
	(aarch64_expand_pragma_builtin): Modify to handle different
	signatures.
	* config/aarch64/aarch64-simd-pragma-builtins.def
	(ENTRY_VHSDF): Rename to ENTRY_BINARY_VHSDF.
	(ENTRY_BINARY): New macro to declare binary intrinsics.
	(ENTRY_BINARY_VHSDF): Remove signature argument and use
	ENTRY_BINARY.
