3243108518 Introduce an new expression, MemberRefExpr, that refers to a 
member of an object. This expression kind is currently used to refer
to properties within an object, but will eventually be extended to
refer to fields as well (once we make StructDecl real).

9009d294d2 More strictly special-case '..'; making '-.' etc. an operator would be a complete disaster.

6a001efbbb Make "..", "*^.^*", etc. into overloadable operators. Make 1..10 construct a Range. 
This has the side-effect that you can't explicitly refer to an operator* with "swift.*", etc., but per discussion with Doug, that's probably okay.

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.

4fc32fd9b4 For a function that is either a getter or setter for a variable, 
provide a mapping back to that variable. Teach the mangler to provide
a special mangling for such functions (__getVarName,
__setVarName). The mangling will undoubtedly change later, but the
point is that it will need to match the functions generated for
a resilient variable.

af2399cd30 Significantly step up the validity asserting around the cleanup stack. 
With that in place, fix ~Scope so that it uses the same code for
popping as Scope::pop() does, i.e. the code that modifies InnermostScope
before popping out.

This properly fixes the issue Doug patched over in r1387.

4c97c19a4f "Fix" a use-after-free when dealing with dead cleanups, where we try 
to look at the first element of an empty stack. The use-after-free
triggers occasionally for me during normal testing (about 1 failure
per 5 trials), but triggers on IRgen/func.swift regularly when using
guardmalloc. 

John, please take a look; this feels more like treating a symptom than
addressing the cause.

f3e27d90ff Change IR-generation so that it emits metadata objects for the 
heap allocations it makes, and switch swift_alloc over to pass
that pointer in as well as the alignment.  Also, compute
whether a type is POD during its generation and cache that in
the object, and introduce a method on TypeInfo to destroy an
object in memory.

65b400e30d introduce a new "Builtin.RawPointer" type, which corresponds to LLVM's "i8*" type,

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.
