    arm: Fix arm_simd_types and MVE scalar_types
    
    So far we define arm_simd_types and scalar_types using type
    definitions like intSI_type_node, etc...
    
    This is causing problems with later patches which re-implement
    load/store MVE intrinsics, leading to error messages such as:
      error: passing argument 1 of 'vst1q_s32' from incompatible pointer type
      note: expected 'int *' but argument is of type 'int32_t *' {aka 'long int *'}
    
    This patch uses get_typenode_from_name (INT32_TYPE) instead, which
    defines the types as appropriate for the target/C library.

            * config/arm/arm-builtins.cc (arm_init_simd_builtin_types): Fix
            initialization of arm_simd_types[].eltype.
            * config/arm/arm-mve-builtins.def (DEF_MVE_TYPE): Fix scalar
            types.
