Implement jump checking for initialized c++ variables, implementing
a fixme and PR6451.
Only perform jump checking if the containing function has no errors,
and add the infrastructure needed to do this.
On the testcase in the PR, we produce:
t.cc:6:3: error: illegal goto into protected scope
goto later;
^
t.cc:7:5: note: jump bypasses variable initialization
