calls.c (prepare_call_address): New parameter SIBCALLP.
* calls.c (prepare_call_address): New parameter SIBCALLP. If true,
don't force the function address into a register.
(expand_call, emit_library_call_value_1): Update callers.
* builtins.c (expand_builtin_apply): Likewise.
* expr.h (prepare_call_address): Update decl.
