static analyzer: Further reduce the analyzer's memory usage when analyzing sqlite3 by 7-10% by recylcing "uninteresting" ExplodedNodes.

The optimization involves eagerly pruning ExplodedNodes from the ExplodedGraph that contain
practically no difference between the predecessor and successor nodes.  For example, if
the state is different between a predecessor and a node, the node is left in.  Only for
the 'environment' component of the state do we not care if the ExplodedNodes are different.
This paves the way for future optimizations where we can reclaim the environment objects.

record away from the core processor record. The tangling of these two
data structures led to some inefficiencies (e.g., deserializing all
of the detailed preprocessing record when we didn't need it, such as
while performing code completion) along with some unnecessary
ugliness.

  - BlockDeclRefExprs always store VarDecls
  - BDREs no longer store copy expressions
  - BlockDecls now store a list of captured variables, information about
    how they're captured, and a copy expression if necessary
    
With that in hand, change IR generation to use the captures data in       
blocks instead of walking the block independently.        

Additionally, optimize block layout by emitting fields in descending
alignment order, with a heuristic for filling in words when alignment
of the end of the block header is insufficient for the most aligned
field.

Fix self-host; if a thunk already exists and has available_externally linkage, we should change its linkage instead of asserting.

llvm-svn: 124986

When building with optimizations, emit thunks with available_externally linkage so devirtualized function calls can also be de-thunked.

overridden via remapping. Thus, when we create a "virtual" file in the
file manager, we still stat() the real file that lives behind it so
that we can provide proper uniquing based on inodes. This helps keep
the file manager much more consistent.

To take advantage of this when reparsing files in libclang, we disable
the use of the stat() cache when reparsing or performing code
completion, since the stat() cache is very likely to be out of date in
this use case.

won't assert when building a thunk for an implicit virtual member function that is not marked used.

llvm-svn: 124967

A common pattern in classes with multiple initializers is to put the
subclass's common initialization bits into a static function that receives
the value of 'self', e.g:

   if (!(self = [super init]))
     return nil;
   if (!(self = _commonInit(self)))
     return nil;

It was reported that 'self' was not set to the result of [super init].
Until we can use inter-procedural analysis, in such a call, transfer the
ObjCSelfInitChecker flags associated with 'self' to the result of the call.
