This is a partial revert of r143846. While cleaning up after a crash is
probably a good idea, we were also deleting .d files if the compilation failed
due to invalid input, which is not the desired behavior. The test is XFAIL'd
until the cleanup code can be reworked to do the right thing.

Objective-C classes. This has two purposes: to consistently provide
"forward declaration here" notes when we hit an incomplete type, and
to give LLDB a chance to complete the type.
RequireCompleteType bits from Sean Callanan!

of the first type is the same as the aka string of the second type, but both
types are different. Update the logic to print an aka for the first type to
show that they are different.

or MemberExpr which refers to it. As a side-effect, MemberExprs which refer to
static member functions and static data members are now emitted as constant
expressions.

it is going to be rewritten (and the chain will be serialized again), otherwise we may form a cycle in its
categories list when deserializing.
Also introduce ASTMutationListener::CompletedObjCForwardRef to notify that a forward reference
was completed; using Decl's isChangedSinceDeserialization/setChangedSinceDeserialization
is bug inducing and kinda gross, we should phase it out.
Fixes infinite loop in rdar://10418538.

into a submodule. Submodules aren't actually supported anywhere else,
but we do parse them, so this verifies that we're at least seeing
through them properly.

the module is described in one of the module maps in a search path or
in a subdirectory off the search path that has the same name as the
module we're looking for.

map, so long as they have an umbrella header. This makes it possible
to introduce a module map + umbrella header for a given set of
headers, to turn it into a module.
There are two major deficiencies here: first, we don't go hunting for
module map files when we just see a module import (so we won't know
about the modules described therein). Second, we don't yet have a way
to build modules that don't have umbrella headers, or have incomplete
umbrella headers.

the corresponding (top-level) modules. This isn't actually useful yet,
because we don't yet have a way to build modules out of module maps.

to disable the corresponding -Wc++98-compat warnings in addition to the C++11
extension warnings, so that people already using these flags can switch to C++11
mode and turn on -Wc++98-compat.

Module map files provide a way to map between headers and modules, so
that we can layer a module system on top of existing headers without
changing those headers at all.
This commit introduces the module map file parser and the module map
that it generates, and wires up the module map file parser so that
we'll automatically find module map files as part of header
search. Note that we don't yet use the information stored in the
module map.
