[patch, fortran] PR46079 ABI for empty stop statement broken

[Jerry DeLisle]

Hi,

I discovered this minor bug while testing for the revamp of the type enumerators.

I think the ChangeLog is clear enough.

Regression tested on x86-64-linux-gnu. No new test case needed.

OK for trunk?

	PR fortran/46079
	* trans_stmt.c (gfc_trans_stop): If the STOP statement is empty,
	build a call to the new function stop_empty.  If integer, build a call
	to stop_string or error_stop_string with a NULL pointer and the
	integer value as the length.
	* trans.h: Add declaration for gfor_fndecl_stop_empty.
	* trans-decl.c (gfc_build_builtin_function_decls): Build declaration
	for stop_empty.

	* runtime/stop.c (stop_empty): New function. (stop_numeric): Restore
