in the checkers just to preserve the standard checks.
Verify the invariants of a TupleElementExpr.

statement walk callback functions, where we can stash additional
information without breaking all of the callers.
At present, the only information in the context is the parent
statement or expression.

function into all of the expression nodes. Re-implement
Expr::getStartLoc() in terms of this function, and add it's brother
Expr::getEndLoc(), removing the specialized implementations.
Clean up the source ranges of implicitly-created tuple expressions in
the process.

aren't needed for the lexer proper (which just needs a buffer to dig
through). Also, make it possible to suppress lexer diagnostics merely
by not giving it a diagnostic engine to work with.

actually render emitted diagnostics. This is both a useful
generalization (we expect to have a number of other
DiagnosticConsumers down the road, as Clang does) and is also
important now to avoid a layering violation when adjusting the source
location at the end of a SourceRange to the end of the token.

Note that I had to re-implement llvm::Optional, since it lamely requires a default constructor. At some point, I'll push a proper implementation back to LLVM.

making it a real part of the AST. Also, rework TUModuleCache to do its computation
when it is constructed, instead of trying in each query.

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.

their ASTContext without bloating everything. Basically, now instead of having
a canonical type point to itself when canonical, it points to the ASTContext
when canonical. This means that Canonical types always have direct access to
their context and non-canonical ones just indirect through the canonical type
pointer to get to it (so it's two jumps away) by using a PointerUnion.
This should make type manipulation more straight-forward.
While we're at it, we actually memoize type canonicalization. Before we
forgot to remember the result in the canonical type pointer in Type.

Also use the new getAdvancedLoc() method instead of hacking
on SMLoc directly.
Also fix the warning/note/error methods to forward through ASTContext
instead of being replicated everywhere.
