According to #87540

The following problems need to be fixed to enable SIMD registers across all Mono codegen engines on Arm64

  • the gshared versions of SIMD types like Vector<T_INT> are not marked as SIMD, so there is a calling convention mismatch if the callee is generic shared.
  • the gsharedvt code doesn't support it, i.e. it asserts in get_arg_slots ().
  • the dyncall code might not support it either.
