e66c13cfe7 Change the 'walk' APIs to use virtual function dispatch 
instead .
1,2d
1i
Change the 'walk' APIs to use virtual dispatch instead of
blocks.  This makes it much easier to thread information
through the API, as well to extend the API to handle
recursive visiting of other structures (e.g., Decls
and Patterns).

ed7062c452 instead of having name binding kill off entire subtrees that contain invalid variable uses, have it turn the ivalid use into an ErrorExpr.

584ed537fc introduce a new ErrorExpr to represent a subexpression that is semantically 
inconsistent (so it needs to be killed) but that we want to retain source
range information and not kill the entire subtree that contains it.

fa2ea94348 always turn a named reference to a type into an IdentifierType. 
This preserving source location info and reduces redundancy in the parser.

51e44891af rip out now-dead code from NameBinding. It still generally needs to be beaten 
into sense later, but this gets it closer to reasonable.

c8ca11a199 Drop in the new DottedNameType and wire it up in name binding. 
This is horribly hack and slash (but enough to pass all tests) for a few reasons:
- I've #if 0'd out the tendrils of the old code 
- This handles *just* what was handled before instead of being more general
- We don't have an llvm::MutableArrayRef type, so there is some really gross
  const_cast'ing and other struggles to deal with its absence.

some redundancy in the code that always has to create an overload set
or a single declrefexpr depending on what various lookups produce.

ModuleExpr of the right  type to represent it.  Not tested yet, because
nothing can handle module exprs.

just works for module references like Builtin::int32.

59bed696a5 Introduce a ParenExpr to represent the special case of 
a tuple with one element and no labels.  This form is
treated specially in essentially every case, so it might
as well be its own expression kind.

we can't just the normal walker for this top-level walking.

623de6cefc now that ModuleProvider is gone, we can match against the module name 
instead of the access path.  Tracking just the access path in the
imports list greatly simplifies all of the client and means that we
don't have to create a bogus ImportDecl for the builtin module just
to make name lookup work.

e3b53c3b15 move the module-level name lookup stuff out of NameBinding.cpp into the 
Module class.  Add a new Module.cpp file to implement this (along with
the existing caching strategy, if you're curious).  This eliminates the
parallel 'ModuleProvider' heirarchy.
