9a8f13961c Revert r142914 and r142915, due to possibly missing file.
r142914: "Introduce a placeholder type for "pseudo object""
r142915: "Pull the pseudo-object stuff into its own file."

c4a2d3259f Introduce a placeholder type for "pseudo object"
expressions: expressions which refer to a logical rather
than a physical l-value, where the logical object is
actually accessed via custom getter/setter code.
A subsequent patch will generalize the AST for these
so that arbitrary "implementing" sub-expressions can
be provided.

Right now the only client is ObjC properties, but
this should be generalizable to similar language
features, e.g. Managed C++'s __property methods.

deb4a2be67 Implement support for dependent Microsoft __if_exists/__if_not_exists
statements. As noted in the documentation for the AST node, the
semantics of __if_exists/__if_not_exists are somewhat different from
the way Visual C++ implements them, because our parsed-template
representation can't accommodate VC++ semantics without serious
contortions. Hopefully this implementation is "good enough".

429ec024f8 [PCH] When visiting preprocessed entities, make it possible to avoid deserializing
preprocessed entities that are #included in the range that we are interested.

This is useful when we are interested in preprocessed entities of a specific file, e.g
when we are annotating tokens. There is also an optimization where we cache the last
result of PreprocessingRecord::getPreprocessedEntitiesInRange and we re-use it if
there is a call with the same range as before.

6a59897d50 [PCH] When serializing Stmts, keep track of when sub statements are referenced again and
in such a case just write out a reference of a previously serialized Stmt, instead
of serializing it all over again.

This saves memory + space + [de]serializing time, and avoids blowing up memory
with pathological cases. rdar://10293911

b8c3aaf479 Allow getting all source locations of selector identifiers in a ObjCMethodDecl.
Instead of always storing all source locations for the selector identifiers
we check whether all the identifiers are in a "standard" position; "standard" position is

  -Immediately before the arguments: -(id)first:(int)x second:(int)y;
  -With a space between the arguments: -(id)first: (int)x second: (int)y;
  -For nullary selectors, immediately before ';': -(void)release;

In such cases we infer the locations instead of storing them.

2fd3d401f9 With modules, we can end up loading a new module after we've seen an
arbitrary amount of code. This forces us to stage the AST writer more
strictly, ensuring that we don't assign a declaration ID to a
declaration until after we're certain that no more modules will get
loaded.

03c40c5182 [PCH] Overhaul how preprocessed entities are [de]serialized.
-Use an array of offsets for all preprocessed entities
-Get rid of the separate array of offsets for just macro definitions;
 for references to macro definitions use an index inside the preprocessed
 entities array.
-Deserialize each preprocessed entity lazily, at first request; not in bulk.

Paves the way for binary searching of preprocessed entities that will offer
efficiency and will simplify things on the libclang side a lot.
