Thanks for the reminder.  Sorry I missed most of them.


I added some -finline-stringops tests that included memcmp-1.c, but
carried over the timeout factor onto only one such test.  Jeff Law
kindly pointed that out (thanks!), so here's the fix.

Testing on x86_64-linux-gnu.  I'll check this in as obvious once testing
is done.

	* gcc.dg/torture/inline-mem-cmp-1.c: Copy timeout factor from
	mem-cmp-1.c.
	* gcc.dg/torture/inline-mem-cpy-1.c: Likewise.

Disinformation flourishes because many people care deeply about injustice but
very few check the facts.  Think Assange & Stallman.  The empires strike back
