calls.c (initialize_argument_information): Add CALL_FROM_THUNK_P parameter.
* calls.c (initialize_argument_information): Add CALL_FROM_THUNK_P
parameter. Use it instead of current_function_is_thunk.
* function.h (struct function): Update documentation for is_thunk.
* tree.h (CALL_FROM_THUNK_P): New macro.
* config/alpha/alpha.c (alpha_sa_mask): Do not check
no_new_pseudos when testing current_function_is_thunk.
* config/rs6000/rs6000.c (rs6000_ra_ever_killed): Likeiwse.
* decl.c (cxx_push_function_context): Do not set
current_function_is_thunk.
* method.c (use_thunk): Set CALL_FROM_THUNK on the call to the
actual function.
