Bug #48406 for Perl-Critic-StricterSubs: ProhibitCallsToUndeclaredSubs vs defined &foo

With the current cvs, a file foo.pl containing defined &foo reports Subroutine "&foo" is neither declared nor explicitly imported where I hoped it could recognise that as an existence test instead of a call. Testing your own package's funcs like that is a bit unusual, but I had it in test scripts which look at the funcs exported (or not) by the thing under test. ProhibitAmpersandSigils has a similar check for defined &foo (with or without parens like defined(&foo) etc). There may be an opportunity to share code as to what's a test or a call.
