783ffde6d3 objc: When issuing warning for missing synthesis for 
properties in classes declared with objc_suppress_autosynthesis
attribute, pinpoint location of the said class in a note.

1fc1c6c307 In non-gc, non-arc mode, property of 'Class' type 
variety is treated as a 'void *'. No need to issue
warning reserved for objc object properties.

to declaresSameEntity(), as a baby step toward tracking forward
declarations of Objective-C classes precisely. Part of

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.

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.

79a91418bd Switch LangOptions over to a .def file that describes header of the 
language options. Use that .def file to declare the LangOptions class
and initialize all of its members, eliminating a source of annoying
initialization bugs.
