Add call stack to unused/uninitialized variable warnings

In commit v2.8.4~32^2~14 (Use cmake::IssueMessage for warnings,
2010-12-07) these warnings became formatted.  It is more informative to
give the full call stack with such warnings.  Also it is easier to
implement warnings with a full call stack because we do not have to
construct a custom backtrace with only the top.
