analyzer: add regression test [PR103685]

PR analyzer/103685 reports a false positive from -Wanalyzer-null-dereference
seen at -O2 with GCC 11.  I can reproduce it with GCC 11, but not with
trunk; this patch adds a reduced test case that reproduces it with
GCC 11 as a regression test for GCC 12 onwards.

gcc/testsuite/ChangeLog:
	PR analyzer/103685
	* gcc.dg/analyzer/torture/pr103685.c: New test.
