Skip -fdelete-null-pointer-check tests if target keeps_null_pointer_checks

A bunch of tests explicitly pass in -fdelete-null-pointer-checks and
 fail if the target keeps null pointer checks. Skip such tests by
adding a dg-skip-if for keeps_null_pointer_checks.

gcc/testsuite/ChangeLog:

	* gcc.dg/attr-returns-nonnull.c: Skip if
	keeps_null_pointer_checks.
	* gcc.dg/init-compare-1.c: Likewise.
	* gcc.dg/ipa/pr85734.c: Likewise.
	* gcc.dg/ipa/propmalloc-1.c: Likewise.
	* gcc.dg/ipa/propmalloc-2.c: Likewise.
	* gcc.dg/ipa/propmalloc-3.c: Likewise.
	* gcc.dg/ipa/propmalloc-4.c: Likewise.
	* gcc.dg/tree-ssa/evrp11.c: Likewise.
	* gcc.dg/tree-ssa/pr83648.c: Likewise.
