36472404b2 Parse swift.swift upfront in the REPL. This has two benefits: one, we error immediately if swift.swift can't be found, or something is wrong with it. Two, it lets us JIT swift.swift upfront, which makes the REPL prompt feel more responsive. <rdar://problem/11305258>.

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.

ba56d2c0b1 Implement support for lookup of members of the current 
oneof/struct/protocol within a static method. The lookup is performed
on the metatype (as one would get when using qualified syntax
Type.member). Add tests to verify that this provides proper
overloading behavior.

As a drive-by, actually set the type of the implicit 'this' variable
during name binding for a non-static method.

c24d6ec8c4 Factor OverloadSetRefExpr into an abstract base class covering the 
notion of a reference to a set of declarations. Introduce one derived
class, OverloadedDeclRefExpr, which covers the only case we currently
handle for overload resolution [*]: a direct (unqualified) reference
to an overloaded set of entities. Future subclasses should handle,
e.g., overloaded member references such as a.b or a.b.c.

[*] Ugly hacks for static methods notwithstanding

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.

e66c13cfe7 Change the 'walk' APIs to use virtual function dispatch 
instead .

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).

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.
