Subject: [PATCH] Make all gcc.dg/guality/const-volatile.c subtests PASS under
 LTO.

Some subtests were reported as UNSUPPORTED when running under LTO.
That was just because the relevant variables were optimized out.
Mark those variables as used. Now const-volatile reports 192 PASS.

gcc/testsuite/ChangeLog

	* gcc.dg/guality/const-volatile.c (i): Mark as used.
	(ci): Likewise.
	(pci): Likewise.
	(pvi): Likewise.
	(pcvi): Likewise.
	(cip): Likewise.
	(foo): Likewise.
	(cfoo): Likewise.
