cd29a77770 introduce a new parseIdentifier method that *just* parses identifiers, 
but not operators.  Audit calls to make sure that we use the right one
in the right places.  This allows us to reject structs named * for example.

7b29a420f6 Design and implement the [byref] attribute, checking that 
it doesn't appear in places it shouldn't.  The only limits on
this checking right now is the inadequacy of location information
for types, which is something we ought to fix.

Fix type-checking of byref applications.  Fix IR generation
of byref variables.  Whole lotta fixin' goin' on.

But hey, byref calls work.

1c7d9f79ba simplify value-specifier code to eliminate the 'expr single' previous special case. 
Since we reworked how expression binding works, this complexity isn't needed anymore.

fc183b9cc3 Decouple the lexer from the ASTContext and specific BufferID. They 
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.

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.

just move the Sema code into the Parser library.  There is no way to use one without
the other.  The library formerly known as Sema will get renamed.
