analyzer: add regression test for PR 107158

PR analyzer/107158 reports an ICE when using
  -fanalyzer -fanalyzer-call-summaries
on a particular source file.

It turns out I just fixed this ICE in r13-3094-g6832c95c0e1a58.

This followup patch adds a somewhat reduced reproducer as a regression
test.  Unfortunately, although the ICE is fixed, there are two false
positives from -Wanalyzer-malloc-leak on the test case, so I'm going to
use PR analyzer/107158 for tracking those false positives.

gcc/testsuite/ChangeLog:
	PR analyzer/107158
	* gcc.dg/analyzer/call-summaries-pr107158.c: New test.
