a glvalue as a temporary. Previously, we were enumerating all of the
cases that coul return glvalues and might be called with
Sema::MaybeBindToTemporary(), but that was gross and we missed the
Objective-C property reference case.

- BlockDeclRefExprs always store VarDecls
- BDREs no longer store copy expressions
- BlockDecls now store a list of captured variables, information about
how they're captured, and a copy expression if necessary
With that in hand, change IR generation to use the captures data in
blocks instead of walking the block independently.
Additionally, optimize block layout by emitting fields in descending
alignment order, with a heuristic for filling in words when alignment
of the end of the block header is insufficient for the most aligned
field.

overridden via remapping. Thus, when we create a "virtual" file in the
file manager, we still stat() the real file that lives behind it so
that we can provide proper uniquing based on inodes. This helps keep
the file manager much more consistent.
To take advantage of this when reparsing files in libclang, we disable
the use of the stat() cache when reparsing or performing code
completion, since the stat() cache is very likely to be out of date in
this use case.

This may not work on build platforms that place the binaries on
special folders ($build_dir/bin/Release/) such as the VS IDE and
XCode. For fixing this it is necessary to add a lit.py configuration
option for saying where the Clang binaries are, and apply to that path
the same magit that is used with the path to the LLVM tools binary
directory. Doing this requires a bit of autoconf work.

This is the first step to make the clang_complete vim plugin work with
libclang. Reparsing improves parsing time from 0.8 to 0.25 secs for
one of my LLVM .cpp files.

The iterator did never throw an IndexError. It was therefore not possible
to use it in a normal foreach loop as that loop would never stop.

This improves the readability of the code and fixes one testsuite bug.
The bug happend, because we only stored the pointer to the diagnostic in the
FixIt iterator, but not the python Diagnostic object. So it could happen that
the FixIt iterator still exists, but the python Diagnostic object is freed.
However, as the python Diagnostic is freed the pointer to the diagnostic is also
freed and the FixIt iterator is referencing a freed pointer.

A common pattern in classes with multiple initializers is to put the
subclass's common initialization bits into a static function that receives
the value of 'self', e.g:
if (!(self = [super init]))
return nil;
if (!(self = _commonInit(self)))
return nil;
It was reported that 'self' was not set to the result of [super init].
Until we can use inter-procedural analysis, in such a call, transfer the
ObjCSelfInitChecker flags associated with 'self' to the result of the call.

the silly "functions that differ only in their return type cannot be overloaded".

id-expression, e.g.,
CurrentClass<T>::member
Previously, if CurrentClass<T> was dependent and not complete, we
would treat it as a dependent-scoped declaration reference expression,
even if CurrentClass<T> referred to the current instantiation.
Fixes PR8966 and improves type checking of templates.
