[analyzer] Move failing 'new' test cases back into new.cpp instead of XFAILing.

Per Anna's comment, this is a better way to handle "to-do list"-type failures.
This way we'll know if any of the features get fixed; in an XFAIL file, /all/
the cases have to be fixed before lit would tell us anything.
