Allow explicit ctors for casts.

When doing overload resolution, expressions that are value dependent but not type dependent and of integral type should not be treated as null pointer constants.

Pass InOverloadResolution all the way down to IsPointerConversion.

Lot's of little changes to get the C-based indexing API going...

Work in progress.

Instantiate unresolved using declarations.

ir-gen related patch for type conversion
with class type conversion methods. WIP.

Add CX prefix to Cursor and move a comment.

Omnibus friend decl refactoring.  Instead of cloning AST classes for friend
declarations of same, introduce a single AST class and add appropriate bits
(encoded in the namespace) for whether a decl is "real" or not.  Much hackery
about previously-declared / not-previously-declared, but it's essentially
mandated by the standard that friends alter lookup, and this is at least
fairly non-intrusive.

Refactor the Sema methods specific to friends for cleaner flow and less nesting.

Incidentally solve a few bugs, but I remain confident that we can put them back.

Create UnresolvedUsingDecls.

Factor declaration building out to Sema::BuildUsingDeclaration.

Check in UnresolvedUsingDecl.

Use SymbolicRegion instead of CodeTextRegion for symbolic function
pointers.  Most logic cares first about whether or not a region is
symbolic, and second if represents code.  This should fix a series of
silent corner case bugs (as well as simplify a bunch of code).

When looking for overloaded member operators, make sure to instantiate
class template specializations (when possible) and look into base
classes. Thanks to Eli for the test case!
