0f2a3607e0 Keep track of all of the import declarations that are parsed or
implicitly generated in a translation unit. Modules will need this
information to identify the actual imports that occurred.

7b8e4bc83f Implement name hiding for macro definitions within modules, such that

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).

253eefe0df Switch the ID numbers used for submodule IDs in the AST reader over to
a standard global/local scheme, so that submodule definitions will
eventually be able to refer to submodules in other top-level
modules. We'll need this functionality soonish.

85825aebc9 Further tweak -Wurneachable-code and templates by allowing the warning to run on
explicit template specializations (which represent actual functions somebody wrote).

Along the way, refactor some other code which similarly cares about whether or
not they are looking at a template instantiation.

b3041feaf7 Revert most of r145372 for now. Lookahead beyond the ';' in a function
declaration tickles a bug in the way we handle visibility pragmas.

The improvement to error recovery for template function definitions declared
with the 'typedef' specifier in r145372 is unrelated and not reverted here.

de3ef502a9 Promote ModuleMap::Module to a namespace-scope class in the Basic
library, since modules cut across all of the libraries. Rename
serialization::Module to serialization::ModuleFile to side-step the
annoying naming conflict. Prune a bunch of ModuleMap.h includes that
are no longer needed (most files only needed the Module type).

b9e53ed4e2 [PCH] In ASTReader::FinishedDeserializing, after we do PassInterestingDeclsToConsumer
we may end up having added more pending stuff to do, so go in a loop until everything

6902197407 Implement (de-)serialization of the description of a module and its
submodules. This information will eventually be used for name hiding
when dealing with submodules. For now, we only use it to ensure that
the module "key" returned when loading a module will always be a
module (rather than occasionally being a FileEntry).

5f4e3a780f Add bigger method type encodings to protocol objects. <rdar://problem/10492418>
The new metadata are method @encode strings with additional data.

1. Each Objective-C object is marked with its class name and protocol names.
The same is done for property @encode already.

2. Each block object is marked with its function prototype's @encoding. For
example, a method parameter that is a block object that itself returns void
and takes an int would look like:
    @?<v@?i>

These new method @encode strings are stored in a single array pointed to by structs protocol_t and objc_protocol_ext.

Patch provided by Greg Parker!

8ad3bab505 [libclang] Fix operations (token annotation, getting cursor, etc.) with a file region
inside an objc container that "contains" other file-level declarations.

When getting the array of file-level declarations that overlap with a file region,
we failed to report that the region overlaps with an objc container, if
the container had other file-level declarations declared lexically inside it.

Fix this by marking such declarations as "isTopLevelDeclInObjCContainer" in the AST
and handling them appropriately.
