i came into conclusion that we need to separate ffi_closure_raw_THISCALL from
ffi_closure_raw_SYSV(not using such as jmp .stubraw), because
ffi_closure_raw_THISCALL is not transparent by CFI so that
_Unwind_RaiseException would not fail with _urc_end_of_stack, modifing CFI of
ffi_closure_raw_THISCALL so that thiscall closure of ffi_closure_raw_THISCALL
would not be shown by reading CFI
