Return a declaration to the parser when creating a field in C++ so that

wasn't a comment, so farewell to all that.

Perform zero-initialization of virtual base classes when emitting

To make this happen, track the field indexes for virtual bases
in the complete object. I'm curious whether we might be better
off making CGRecordLayoutBuilder *much* more reliant on
ASTRecordLayout; we're currently duplicating an awful lot of the ABI
layout logic.

[analyzer] Overhauling of the checker registration mechanism.
-Checkers will be defined in the tablegen file 'Checkers.td'.
-Apart from checkers, we can define checker "packages" that will contain a collection of checkers.
-Checkers can be enabled with -analyzer-checker=<name> and disabled with -analyzer-disable-checker=<name> e.g:
Enable checkers from 'cocoa' and 'corefoundation' packages except the self-initialization checker:
-analyzer-checker=cocoa -analyzer-checker=corefoundation -analyzer-disable-checker=cocoa.SelfInit
-Introduces CheckerManager and CheckerProvider. CheckerProviders get the set of checker names to enable/disable and
register them with the CheckerManager which will be the entry point for all checker-related functionality.
Currently only the self-initialization checker takes advantage of the new mechanism.

When parsing an out-of-line member function declaration, we must delay
access-control diagnostics which arise from the portion of the declarator
following the scope specifier, just in case access is granted by
friending the individual method. This can also happen with in-line
member function declarations of class templates due to templated-scope
friend declarations.
We were really playing fast-and-loose before with this sort of thing,
and it turned out to work because *most* friend functions are in file
scope. Making us delay regardless of context exposed several bugs with
how we were manipulating delay. I ended up needing a concept of a
context that's independent of the declarations in which it appears,
and then I actually had to make some things save contexts correctly,
but delay should be much cleaner now.
I also encapsulated all the delayed-diagnostics machinery in a single
subobject of Sema; this is a pattern we might want to consider rolling
out to other components of Sema.

Improves Clang's virtual file handling.
This patch contains:
- making some of the existing comments more accurate in the presence
of virtual files/directories.
- renaming some private data members of FileManager to match their roles better.
- creating 'DirectorEntry's for the parent directories of virtual
files, such that we can tell whether two virtual files are from the
same directory. This is useful for injecting virtual files whose
directories don't exist in the real file system.
- minor clean-ups and adding comments for class
FileManager::UniqueDirContainer and FileManager::UniqueFileContainer.
- adding statistics on virtual files to FileManager::PrintStats().
- adding unit tests to verify the existing and new behavior of FileManager.
