127f6eef7e [-E] Emit a rewritten _Pragma on its own line. 
1. Teach Lexer that pragma lexers are like macro expansions at EOF.
2. Treat pragmas like #define/#undef when printing.
3. If we just printed a directive, add a newline before any more tokens.
(4. Miscellaneous cleanup in PrintPreprocessedOutput.cpp)

e0763c7472 ARM: optimization for sub+abs. 
This patch will optimize abs(x-y)
FROM
sub, movs, rsbmi
TO
subs, rsbmi

For abs, we will use cmp instead of movs. This is necessary because we already
have an existing peephole pass which optimizes away cmp following sub.

8370c7c38f LSR: fix expansion of scaled reg in non-address type formulae. 
For non-address users, Base and Scaled registers are not specially
associated to fit an address mode, so SCEVExpander should apply normal
expansion rules. Otherwise we may sink computation into inner loops
that have already been optimized.

9da05858b4 [completion] Add completions for @"..." and @(...), and tidy up @[] and @{}. 
Specifically, @[] and @{} didn't have a type associated with them; we now
use "NSArray *" and "NSDictionary *", respectively. @"" has the type
"NSString *". @(), unfortunately, has type "id", since it (currently) may
be either an NSNumber or an NSString.

Add a test for all the Objective-C at-expression completions.

95dfae824e [analyzer] RetainCount: don't track objects init'd with a delegate 
We already didn't track objects that have delegates or callbacks or
objects that are passed through void * "context pointers". It's a
not-uncommon pattern to release the object in its callback, and so
the leak message we give is not very helpful.

2684c68ddc Warn when a static variable is referenced in a non-static inline function. 
This is explicitly forbidden in C99 6.7.4p3. This is /not/ forbidden in C++,
probably because by default file-scope const/constexpr variables have internal
linkage, while functions have external linkage. There's also the issue of
anonymous namespaces to consider. Nevertheless, there should probably be a
similar warning, since the semantics of inlining a function that references
a variable with internal linkage do not seem well-defined.

1821c6c3b0 Some optimizations done by globalopt are safe only for internal linkage, not 
linkonce linkage. For example, it is not valid to add unnamed_addr.
