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.

d68fee8b41 Perform Builtin.load and Builtin.store using the type 
info for the result/argument type.  This makes them
properly generic over an arbitrary type.

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.

5e38419345 In a currying forwarder, force the release of the data allocation 
between the point at which values were loaded out and the point
at which the call is performed.  This is bad for some things,
like not spilling all the arguments, and good for others, like
not keeping the allocation around unnecessarily and being able
to do a tail call.

This has the side-effect of causing the release to actually occur,
since we're not doing cleanups yet.

173d750a02 Switch IR-generation to use ASTVisitor, or more precisely, to 
use irgen::ASTVisitor, which is a subclass of the AST version
that always looks through some expressions and asserts that
others (the unchecked/error ones) can't happen.  The main
obstacle to that is access control, because it's quite nice to
have the visitor be a non-local class for nesting purposes,
but that makes it impossible to use private methods anymore.
It's nice to give all the type-specific emitters private
interfaces anyway, though;  that ends up being most of the
patch.

I futzed with GenClosure.cpp while I was in there, but
separating it would have been obnoxious.

locals to the heap if they've been referenced in a way that requires
this.

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.

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.

16f8b2e656 Revise the language design for function argument clause syntax. 
A function argument clause is now one or more patterns (which
must be parenthesized and explicitly type all positions) not
separated by arrows;  the first arrow then separates off the
return type.

Revisions to language reference forthcoming.
