Move uninitialized variable checking back under -Wuninitialized-experimental.  It is clear from user feedback that this warning is not quite ready.

  - 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.

Fix self-host; if a thunk already exists and has available_externally linkage, we should change its linkage instead of asserting.

When building with optimizations, emit thunks with available_externally linkage so devirtualized function calls can also be de-thunked.

It is not possible to simply change that target name to `clang'

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completion, since the stat() cache is very likely to be out of date in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.

Basic implementation of inherited constructors. Only generates declarations, and probably only works for very basic use cases.

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.

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.

clang-c/Index.h contained cursor kinds not yet available in the python bindings.

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.
