    Add support for objc property decls according to the page at:

    http://llvm.org/docs/SourceLevelDebugging.html#objcproperty

    including type and DECL. Expand the getter and setter names
    into the fully qualified names.

Make ModuleMapParser own its TargetInfo, so it doesn't get leaked.

Tidy.

Go back to using just the selector name for the getter and setter
in the property debug info. Any more isn't necessary after all.

Call out to GCC-compatible runtime functions for atomic ops that we can't use
LLVM intrinsics for.

I have an implementation of these functions, which wants to go in a libgcc_s
equivalent in compiler-rt.  It's currently here:

http://people.freebsd.org/~theraven/atomic.c

It will be committed to compiler-rt as soon as I work out where would be a
sensible place to put it...

[libclang] Have c-index-test output more information about a cursor with -cursor-at:

-the location of the cursor

-its spelling

[libclang] A MemberRefExpr cursor for a property dot syntax should have as
its location the location of the property.

Part of rdar://11113120

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153708 91177308-0d34-0410-b5e6-96231b3b80d8
Add info to ObjCPropertyRefExpr to indicate whether the dot syntax property
reference is going to message the setter, the getter, or both.

Having this info on the ObjCPropertyRefExpr node makes it easier for AST
clients (like libclang) to reason about the meaning of the property reference.

[AST/Sema]
-Use 2 bits (with a PointerIntPair) in ObjCPropertyRefExpr to record the above info
-Have ObjCPropertyOpBuilder set the info appropriately.

[libclang]
-When there is an implicit property reference (property syntax using methods)
have clang_getCursorReferenced return a cursor for the method. If the property
reference is going to result in messaging both the getter and the setter choose
to return a cursor for the setter because it is less obvious from source inspection
that the setter is getting called.

The general idea has the seal of approval by John.
