[testsuite/guality] Don't use attribute used in pr45882.c for -O0

2018-06-30  Tom de Vries  <tdevries@suse.de>

	* gcc.dg/guality/guality.exp (guality_transform_options): New proc.
	(toplevel): Apply guality_transform_options on DG_TORTURE_OPTIONS and
	LTO_TORTURE_OPTIONS.
	* gcc.dg/guality/prevent-optimization.h: New file.
	* gcc.dg/guality/pr45882.c: Include prevent-optimization.h.
	(a): Replace __attribute__((used)) with ATTRIBUTE_USED.
