x86: Issue error for return/argument only with function body
If we never generate function body, we shouldn't issue errors for return
nor argument. Add silent_p to i386 machine_function to avoid issuing
errors for return and argument without function body.

* config/i386/i386-options.c (ix86_init_machine_status): Set
silent_p to true.
* config/i386/i386.c (init_cumulative_args): Set silent_p to
false.
(construct_container): Return early for return and argument
errors if silent_p is true.
* config/i386/i386.h (machine_function): Add silent_p.
