Jordan Rose 6d671cc34a [analyzer] Always include destructors in the analysis CFG.
While destructors will continue to not be inlined (unless the analyzer
config option 'c++-inlining' is set to 'destructors'), leaving them out
of the CFG is an incomplete model of the behavior of an object, and
can cause false positive warnings (like PR13751, now working).

Destructors for temporaries are still not on by default, since
(a) we haven't actually checked this code to be sure it's fully correct
    (in particular, we probably need to be very careful with regard to
    lifetime-extension when a temporary is bound to a reference,
    C++11 [class.temporary]p5), and
(b) ExprEngine doesn't actually do anything when it sees a temporary
    destructor in the CFG -- not even invalidate the object region.

To enable temporary destructors, set the 'cfg-temporary-dtors' analyzer
config option to '1'. The old -cfg-add-implicit-dtors cc1 option, which
controlled all implicit destructors, has been removed.

Argyrios Kyrtzidis 57d736fd46 [analyzer] Use the new registration mechanism for the debugging info "checks".
The relative checker package is 'debug':

'-dump-live-variables' is replaced by '-analyzer-checker=debug.DumpLiveVars'
'-cfg-view' is replaced by '-analyzer-checker=debug.ViewCFG'
'-cfg-dump' is replaced by '-analyzer-checker=debug.DumpCFG'

Marcin Swiderski 01769904d3 Added generation of destructors for member constant size arrays.
There's only one destructor call generated for each not empty array (at least for now this should be enough).
