    arm: Move arm_simd_info array declaration into header
    
    Move the arm_simd_type and arm_type_qualifiers enums, and
    arm_simd_info struct from arm-builtins.c into arm-builtins.h header.
    
    This is a first step towards internalising the type definitions for
    MVE predicate, vector, and tuple types.  By moving arm_simd_types into
    a header, we allow future patches to use these type trees externally
    to arm-builtins.c, which is a crucial step towards developing an MVE
    intrinsics framework similar to the current SVE implementation.
    
    gcc/ChangeLog:
    
            * config/arm/arm-builtins.c (enum arm_type_qualifiers): Move to
            arm_builtins.h.
            (enum arm_simd_type): Move to arm-builtins.h.
            (struct arm_simd_type_info): Move to arm-builtins.h.
            * config/arm/arm-builtins.h (enum arm_simd_type): Move from
            arm-builtins.c.
            (enum arm_type_qualifiers): Move from arm-builtins.c.
            (struct arm_simd_type_info): Move from arm-builtins.c.
