George Karpenkov 3e4f379cb6 [CSA] [NFC] Move AnalysisContext.h to AnalysisDeclContext.h 
The implementation is in AnalysisDeclContext.cpp and the class is called
AnalysisDeclContext.

Making those match up has numerous benefits, including:

 - Easier jump from header to/from implementation.
 - Easily identify filename from class.

These ExprWithCleanups are added for holding a RunCleanupsScope not
for destructor calls; rather, they are for lifetime marks. This requires
ExprWithCleanups to keep a bit to indicate whether it have cleanups with
side effects (e.g. dtor calls).

David Blaikie dbe3712f62 unique_ptrify ConsumedBlockInfo analysis to make it move assignable 
ConsumedBlockInfo objects were move assigned, but only in a state where
the dtor was a no-op anyway. Subtle and easily could've happened in ways
that wouldn't've been safe - so this change makes it safe no matter what
state the ConsumedBlockInfo object is in.

Artyom Skrobov 8e28c5794a Use the proper post-order traversal in LiveVariables analysis, 
to recover the performance after r214064.

Also sorts out the naming for PostOrderCFGView, ReversePostOrderCFGView,
BackwardDataflowWorklist and ForwardDataflowWorklist, to match the accepted
terminology.

Also unifies BackwardDataflowWorklist and ForwardDataflowWorklist to share
the "worklist for prioritization, post-order traversal for fallback" logic,
and to avoid repetitive sorting.

Also cleans up comments in the affected area.

Chris Wailes 1aa89697dc Fixed bug with checking the kind of types. 
The isLValueReferenceType function checks to see if the QualType's
canonical type is an LValue reference, and not if the QualType
itself is an LValue reference.  This caused a segfault when trying
to cast the QualType's Type to a LValueReference.  This is now
fixed by casting the result of getCanonicalType().

In addition, a test was added to isConsumableType to prevent
segfaults when a type being tested by the analysis is a reference
to a pointer or a pointer to a reference.
