58b4a5d7cc have the parser produce ErrorStmt nodes to handle semantic errors... 
except that it never produces semantic errors.  How about that.

6692cba150 simplify expression parsing to return a NullablePtr<Expr> instead of a ParseError<Expr>. 
The later could represent semantic errors, but we'd rather represent those with an
ExprError node instead.  This simplifies the code and allows the parser to build a more
fully-formed AST that IDE clients will like.

2b65cf22d1 Make 'this' implicitly [byref] when the container type does 
not have reference semantics.  Deciding whether the container
type has reference semantics requires us to perform
some amount of limited name-binding and type-checking first,
which introduces a few complexities.

Also, fix a bug in uncurried call emission.

Methods work now.

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.

0223f3edf1 Implement Expr::getSourceRange() and introduce proper support for this 
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.

declarations, but they are explicitly allowed at translation unit scope.
This also introduces a parseDecl method which does the obvious thing.

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.

3d15bf3d55 Introduce a diagnostic-formatting engine and port most of the parser's 
diagnostics over to it.

There are a few differences between this diagnostic engine and Clang's
engine:
  - Diagnostics are specified by a .def file (Diagnostics.def), rather
  than via tblgen, which drastically simplifies the build and makes
  code completion work when you add a new diagnostic.
  - Calls to the "diagnose()" method are safely typed based on the
  argument types specified in the .def file, so it's harder to write a
  diagnostic whose expected arguments (in the string) and whose actual
  arguments (in the code) don't match.
  - It uses variadic templates, so it hangs with the cool kids.

26f66a8b24 move all the parser headers into lib/Parse since they are now all private. 
I chose to just delete the -lex action in swift, since it was only useful for
about 10 minutes during bringup and probably never will be again.
