6897b6ab44 Add support for parsing a subscripting declaration, e.g., 
subscript (i : Int) -> Double {
    get { /* get ith element of something */ }
    set { /* set ith element of something to value*/ }
  }

e6d56fd718 Require an unspaced [ to start a subscript or array-type suffix. 
Per discussion, this should probably be "no newline since the last
token", but that decision should be made simultaneously for ( and [.

37de44a35d Implement changes to parsing/sema/etc so that we can implement a REPL and the main module parses the same way as a REPL. 
Next step: implement an actual REPL.

f477cf588e Introduce the notion of the "main" module, i.e. the module which defines main(). Disallow top-level statements in modules other than the main module. Fix IRGen to generate a main() function in the main module, and implement top-level statements. Get rid of the main() mangling hack. Part of <rdar://problem/11185451>. 
I haven't really carefully considered whether existing type-checking etc. is correct for the main module (I think the name-binding rules need to be a bit different?), but it seems to work well enough for the obvious cases.

This is enough to get the one-liner "println(10)" to print "10" in "swift -i" mode, although the path to swift.swift still needs to be explicitly provided with -I.

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.

treated specially in essentially every case, so it might
as well be its own expression kind.

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.

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.
