Hi!

As mentioned in PR63892, with the addition of ICF the sibcall-{3,4}.c tests
no longer test what they meant to test.  This patch duplicates the tests
and adds a volatile var bump in just one of the functions so that ICF can't
be performed and the tests really test sibcalls rather than say tail
recursion.

Regtested on x86_64-linux and i686-linux, ok for trunk?

	* gcc.dg/sibcall-9.c: New test.
	* gcc.dg/sibcall-10.c: New test.

OK.
Jeff
