Extend ExternalASTSource with the ability to lazily complete the
definition of an Objective-C class. Unlike with C/C++ classes, we
don't have a well-defined point in Sema where Objective-C classes are
checked for completeness, nor do we need to involve Sema when
completing a class. Therefore, we take the appropriate of having the
external AST source mark a particular Objective-C class as having an
external declaration; when using one of the accessors of an
Objective-C class that has an external declaration, we request that
the external AST source fill in the Objective-C class definition.

Improve our handling of cv-qualifiers in Objective-C pointer
conversions. Previously, we would end up collapsing qualification
conversions into the Objective-C pointer conversion step, including
(possibly) stripping qualifiers that shouldn't be removed.

This generalizes BuildSimilarlyQualifiedPointerType() to also work on
Objective-C object pointers, then eliminates the (redundant, not
totally correct) BuildSimilarlyQualifiedObjCObjectPointerType()
function.

disambiguate between an expression (for a bit-field width) and a type

tighten up operator= to ensure we don't get multiple owners with the same FD.
wouldn't move ctors be nice? :)

Add GCC 4.4.5 for Gentoo, and order them in a more sensible way. This allows
Gentoo systems with multiple versions to pick up the newest one first. This is
especially important with Gentoo because some of the older versions are left on
systems in strange states.
