testsuite: Make sure the *san/inline* tests aren't UNRESOLVED with LTO

testsuite: Make sure the *san/inline* tests aren't UNRESOLVED with LTO

These tests are UNRESOLVED because -fdump-tree-optimized can't be scanned
with slim LTO.  Other *san/ tests deal with this by adding -ffat-lto-objects.

	* c-c++-common/asan/inline.c: Add -ffat-lto-objects to dg-options.
	* c-c++-common/asan/inline-kernel.c: Likewise.
	* c-c++-common/ubsan/inline.c: Likewise.
