Fix blkarg.c test to fail even on alpha.

Make blkarg.c an expected failure.
Fix driver.c to use exit()/abort().

From-SVN: r25002

gcc/testsuite/gcc.c-torture/ChangeLog

+1999-02-03  Nick Clifton  <nickc@cygnus.com>
+
+	* execute/memcheck/blkarg.c (foo): Use 10 leading arguments in
+	order to force structure S onto the stack even on the alpha.
+	(test): Pass 10 leading arguments to function foo as well as the
+	structure S.
+
+	* execute/memcheck/blkarg.x: New file: Expected failure for all
+	targets. 
+
+	* execute/memcheck/driver.c (main): Use exit or abort to terminate
+	program execution.

 	* execute/990128-1.c: New test.
