...by synthesizing their body to be "return self->_prop;", with an extra
nudge to RetainCountChecker to still treat the value as +0 if we have no
other information.
This doesn't handle weak properties, but that's mostly correct anyway,
since they can go to nil at any time. This also doesn't apply to properties
whose implementations we can't see, since they may not be backed by an
ivar at all. And finally, this doesn't handle properties of C++ class type,
because we can't invoke the copy constructor. (Sema has actually done this
work already, but the AST it synthesizes is one the analyzer doesn't quite
handle -- it has an rvalue DeclRefExpr.)
Modeling setters is likely to be more difficult (since it requires
handling strong/copy), but not impossible.

which may belong to unrelated classes. It was
primarily intended for miuse of @selector expression.
But warning is too noisy and will be issued when
an actual @selector is used. // rdar://15740134

We take loops like this and check that the symbolic strides 'Strided1/2' are one
and drop to the scalar loop if they are not.
This is currently disabled by default and hidden behind the flag
'enable-mem-access-versioning'.

An upcoming loop vectorizer commit will want to replace a SCEVUnknown(Value*)
by a SCEVConstant. This commit modifies the SCEVParameterRewriter to support
this. The SCEVParameterRewriter constructor can optionally specify to follow
this behavior.

The disassembler would no longer be able to disambiguage between the two
variants (explicit immediate #0 vs implicit, omitted #0) for the ldrt, strt,
ldrbt, strbt mnemonics as both versions indicated the disassembler routine.

With this change tok::code_completion is finally handled exclusively as a
special token kind like other tokens that need special treatment.
All callers have been updated to use the specific token consumption methods and
the parser has a clear idea the current token isn't special by the time
ConsumeToken() gets called, so this has been unreachable for some time.
ConsumeAnyToken() behaviour is unchanged and will continue to support
unexpected code completion as part of the special token path.
This survived an amount of fuzzing and validation, but please ping the list if
you hit a code path that previously relied on the old unexpected handler and
now asserts.

Based on recent discussions, attempt to provide a clearer distinction between
MicrosoftMode and MicrosoftExt. This still doesn't feel perfect but gives a
better idea which is which.
Also update the CPlusPlus11 description which got missed in r171367.
C++0x is dead, long live C++0x!

Module-definition (.def) files are the file containing linker directives,
such as export symbols. Because link.exe supports the same features as command
line options, just as some Linker Script commands overlaps with command line
options, use of module-definition file is not really necessary. It provides
an alternative way to specify some linker options.
This patch implements EXPORTS directive. Other directives will be implemented
in the future.

Before:
SomeMap[std::pair(aaaaaaaaaaaa, bbbbbbbbbbbbbbb)]
.insert(ccccccccccccccccccccccc);
After:
SomeMap[std::pair(aaaaaaaaaaaa, bbbbbbbbbbbbbbb)].insert(
ccccccccccccccccccccccc);
This seems to be about 3:1 more common in Google and Chromium style and I found
only a handful of instances inside the LLVM codebase.
