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).

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.

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.

consumable objects. These are useful for implementing error codes that
must be checked. Patch also includes some significant refactoring, which was
necesary to implement the new behavior.

encodes the canonical rules for LLVM's style. I noticed this had drifted
quite a bit when cleaning up LLVM, so wanted to clean up Clang as well.

to determine if a move function is the std::move function. This allows functions
like std::__1::move to also be treated a the move function.

Earlier versions discarded the state too soon, and did not track state changes,
e.g. when passing a temporary to a move constructor. Patch by

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.

marked all variables as "unknown" at the start of a loop. The new version
keeps the initial state of variables unchanged, but issues a warning if the
state at the end of the loop is different from the state at the beginning.
This patch will eventually be replaced with a more precise analysis.

needed and makes writing more complicated behaviour less burdensome.
