dcf910f20c C++: Use EscapesTree to find pointers to stack 
This simplifies the query and is a strict improvement on the tests. I
also found it to be an overall improvement on real projects.

9ac8d60636 C++: IR query for redundant null check 
This new query is not written because it's the most interesting query we
could write but because it's an IR-based query whose results are easy to
verify.

2550788598 C++: Accept test changes to getRelativePath 
After a `queries.xml` was added to the test directory,
`Container.getRelativePath` now considers source files to be relative to
the `cpp/test` directory rather than the directory of the `*.ql*` file.
This caused some benign test output changes, and it also caused an
unwanted alert for `test3.c:14` to appear in
`cpp/ql/test/query-tests/Security/CWE/CWE-190/semmle/tainted/IntegerOverflowTainted.expected`.
This alert came about because `inSystemMacroExpansion` holds for files
that don't have a relative path, but the pretend system header in
`../system_header` now does have a relative path because it's below the
`cpp/test` directory. The fix is to add another `queries.xml` just for
the directory with the affected test.
