arm: Declare MVE types internally via pragma
Move the implementation of MVE ACLE types from arm_mve_types.h to
inside GCC via a new pragma, which replaces the prior type
definitions. This allows for the types to be used internally for
intrinsic function definitions.
gcc/ChangeLog:
* config.gcc (arm*-*-*): Add arm-mve-builtins.o to extra_objs.
* config/arm/arm-c.c (arm_pragma_arm): Handle "#pragma GCC arm".
(arm_register_target_pragmas): Register it.
* config/arm/arm-protos.h: (arm_mve::arm_handle_mve_types_h): New
prototype.
* config/arm/arm_mve_types.h: Replace MVE type definitions with
new pragma.
* config/arm/t-arm: (arm-mve-builtins.o): New target rule.
* config/arm/arm-mve-builtins.cc: New file.
* config/arm/arm-mve-builtins.def: New file.
* config/arm/arm-mve-builtins.h: New file.
gcc/testsuite/ChangeLog:
* gcc.target/arm/mve/mve.exp: Add new subdirectories.
* gcc.target/arm/mve/general-c/type_redef_1.c: New test.
* gcc.target/arm/mve/general/double_pragmas_1.c: New test.
* gcc.target/arm/mve/general/nomve_1.c: New test.
