* config/i386/i386.c (ix86_function_ok_for_sibcall): Allow
indirect sibcall with register arguments if register available
for argument passing.
(init_cumulative_args): Set cfun->machine->arg_reg_available
to (cum->nregs > 0) or to true if function has a variable
argument list.
(function_arg_advance_32): Set cfun->machine->arg_reg_available
to false if cum->nregs <= 0.
* config/i386/i386.h (machine_function): Add arg_reg_available.
