the various stakeholders bump up the reference count. In particular,
the diagnostics engine now keeps the DiagnosticOptions object alive.

4b29c16eec Allow clients of the AST reader to specify what kinds of AST load
failures they know how to tolerate, e.g., out-of-date input files or
configuration/version mismatches. Suppress the corresponding
diagnostics if the client can handle it.

No clients actually use this functionality, yet.

3c717b459b Delete temporary output files when an error occurs during PCH reading.
This reduces the spam make test leaves behind in /tmp. The assert isn't
particularly useful because it's not run with -disable-free (the default when
using the clang driver) but should cover all -cc1 tests.

cb28f9d7ad Rework the (de-)serialization of macros, as stored in
MacroInfo*. Instead of simply dumping an offset into the current file,
give each macro definition a proper ID with all of the standard
modules-remapping facilities. Additionally, when a macro is modified
in a subsequent AST file (e.g., #undef'ing a macro loaded from another
module or from a precompiled header), provide a macro update record
rather than rewriting the entire macro definition. This gives us
greater consistency with the way we handle declarations, and ties
together macro definitions much more cleanly.

Note that we're still not actually deserializing macro history (we
never were), but it's far easy to do properly now.

3292d06a1b Add a new libclang completion API to get brief documentation comment that is
attached to a declaration in the completion string.

Since extracting comments isn't free, a new code completion option is
introduced.

A new code completion option that enables including brief comments
into CodeCompletionString should be a, err, code completion option.
But because ASTUnit caches global declarations during parsing before
even completion consumer is created, the option is duplicated as a
translation unit option (in both libclang and ASTUnit, like the option
to cache code completion results).

CompilerInstance::setCodeCompletionConsumer instead, in order to change
the SkipFunctionBodies flag accordingly. Also fixed

4a280ff48f [PCH] Mark a PCH file with a flag to indicate if the serialized AST had
compiler errors or not.

-Control whether ASTReader should reject such a PCH by a boolean flag at ASTReader's creation time.
By default, such a PCH file will be rejected with an error when trying to load it.

[libclang] Allow clang_saveTranslationUnit to create a PCH file even if compiler errors
occurred.
-Have libclang API calls accept a PCH that had compiler errors.

The general idea is that we want libclang to stay functional even if a PCH had a compiler error.

ae77b3dfad Frontend: Default to creating output files using temporary files + rename.
- This is a more reliable default, as it behaves better on failure and also
   ensures that we create *new* files (instead of reusing existing inodes). This
   is useful for other applications (like lldb) which want to cache inode's to
   know when a file has been rewritten.

getModuleFileName()). No functionality change.

a686e1b05d Introduce module attributes into the module map grammar, along with a
single attribute ("system") that allows us to mark a module as being a
"system" module. Each of the headers that makes up a system module is
considered to be a system header, so that we (for example) suppress
warnings there.

If a module is being inferred for a framework, and that framework
directory is within a system frameworks directory, infer it as a
system framework.

1fb5c3a63a Implement support for module requirements, which indicate the language
features needed for a particular module to be available. This allows
mixed-language modules, where certain headers only work under some
language variants (e.g., in C++, std.tuple might only be available in
C++11 mode).

98a52db80c Detect when mapping a #include/#import over to a submodule ends up
hitting a submodule that was never actually created, e.g., because
that header wasn't parsed. In such cases, complain (because the
module's umbrella headers don't cover everything) and fall back to
including the header.

Later, we'll add a warning at module-build time to catch all such
cases. However, this fallback is important to eliminate assertions in
the ASTWriter when this happens.

7910d7b72a Make changes to SDiagsWriter to make it work in combination with the ARC migrator:
-Allow it to be used with multiple BeginSourceFile/EndSourceFile calls; for this introduce
 a "finish" callback method in the DiagnosticConsumer. SDiagsWriter finishes up the serialization
 file inside this method.
-Make it independent of any particular DiagnosticsEngine; make it use the SourceManager of the
 Diagnostic object.
-Ignore null source ranges.

ff2be53f8f Introduce the notion of name visibility into modules. For a given
(sub)module, all of the names may be hidden, just the macro names may
be exposed (for example, after the preprocessor has seen the import of
the module but the parser has not), or all of the names may be
exposed. Importing a module makes its names, and the names in any of
its non-explicit submodules, visible to name lookup (transitively).

This commit only introduces the notion of name visible and marks
modules and submodules as visible when they are imported. The actual
name-hiding logic in the AST reader will follow (along with test cases).
