The gcc.dg/analyzer/data-model-4.c and
gcc.dg/analyzer/torture/conftest-1.c fail with recent glibc headers
and succeed with older headers.
The new error message is:
warning: use of possibly-NULL 'f' where non-null expected [CWE-690]
[-Wanalyzer-possible-null-argument]
Like similar previous fixes in this area, this patch updates the
testcase so that this warning isn't reported.

* gcc.dg/analyzer/data-model-4.c: Exit if fopen returns NULL.
* gcc.dg/analyzer/torture/conftest-1.c: Likewise.
