count.
This is an optimization for "retry without inlining" option. Here, if we
failed to inline a function due to reaching the basic block max count,
we are going to store this information and not try to inline it
again in the translation unit. This can be viewed as a function summary.
On sqlite, with this optimization, we are 30% faster then before and
cover 10% more basic blocks (partially because the number of times we
reach timeout is decreased by 20%).

the case that the variable already exists. Partly this is just
protection against people making crazy declarations with custom
asm labels or extern "C" names that intentionally collide with
the manglings of such variables, but the main reason is that we
can actually emit a static local variable twice with the
requirement that it match up. There may be other cases with
(e.g.) the various nested functions, but the main exemplar is
with constructor variants, where we can be forced into
double-emitting the function body under certain circumstances
like (currently) the presence of virtual bases.

property file/line rather than the @synthesize file/line. Avoids
some nasty confusing-ness with conflating the file from the scope
and the line from the original declaration.
Update a couple of testcases accordingly since I had to change
that we actually use the passed in location in EmitFunctionStart.

section. A 'normal' string will go into the __TEXT,__const section, but this
isn't good for UTF16 strings. The __ustring section allows for coalescing, among
other niceties (such as allowing the linker to easily split up strings).
Instead of outputting the UTF16 string as a series of bytes, output it as a
series of shorts. The back-end will then nicely place the UTF16 string into the
correct section, because it's a mensch.

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.

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...

concerning qualified declarator-ids. We now diagnose extraneous
qualification at namespace scope (which we had previously missed) and
diagnose these qualification errors for all kinds of declarations; it
was rather uneven before. Fixes <rdar://problem/11135644>.

search for the specialization (in a folding set) and, if not found
form a *Decl that is then inserted into that folding set. In rare
cases, the folding set may be reallocated between the search and the
insertion, causing a crash. No test case, because triggering rehashing
consistently in a small test case is not feasible. Fixes
<rdar://problem/11115071>.
