113aa3d1ff Fix the emission of MemberRefExpr l-values and getter/setter 
pairs in extensions.  The AST here is a little wierd;  I don't
really get why there needs to be a PatternBindingDecl here.
It's easy enough to ignore.

6cdecc020c Make all the subscripting getters/setters go down the same path. 
This intentionally changes the mangling of variable getters and
setters so that we can have a reproducible mangling that doesn't
depend on things like the variables names, which is important
for resilience.  It's not currently important for subscripting,
although equally I see no reason to mangle in the subscript
pattern name.

85fecab3b1 Reorganize the emission of a call site so that it's abstracted over 
exactly how the arguments are emitted.  Introduce a new code path
which emits arguments from existing Explosions (possibly of the wrong
resilience level).  Use that code path to implement getter/setter
code for MemberRefExpr l-values.  This is just a checkpoint for the
latter two parts, but the ApplyExpr path is working correctly in the
new framework, which is worth a commit.

bc32a8aedb Fix a bug with returning value that need to be refcounted: 
we want to do a take-load out of the return address slot
instead of a normal load, or else we'll end up +1'ing an
already +1 value.

properly generic over an arbitrary type.

b7b8f171b3 Treat a function application A(b) as a coercion of the expression 'b' 
to the type named by A (when A is in fact a direct reference to a

constructor. Fixes <rdar://problem/11272190>.

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).

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.

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.
