handling non-fixed layouts.
This uncovered a bug where we weren't rounding up the header
size to the element alignment when allocating an array of archetypes.
Writing up a detailed test case for *that* revealed that we were
never initializing the length field of heap arrays. Fixing that
caused a bunch of tests to crash trying to release stuff. So...
I've left this in a workaround state right now because I have to
catch a plane.

Implement ElementAddrInst for lvalue tuples, and implement the AllocArray, IndexAddr, and IntegerValue insts used to lower variadic tuples. (Actually compiling code that uses variadic tuples still requires support for SpecializeInst and generic functions.)
Swift SVN r3781
Implement SIL-to-IR lowering for allocation, deallocation, load, store, and branching instructions so that local variables and branching control flow can be used. Add a Fibonacci loop test to exercise the new instructions.
Swift SVN r3767
Add a path through IRGenModule to optionally codegen FuncDecls using their corresponding SIL Functions when constructed with a SILModule. Jury-rig an IRGenSILFunction subclass of IRGenFunction that does the bare minimum necessary to compile "hello world" from SIL. There are some impedance mismatches between irgen and SIL that need to be smoothed out, particularly the AST-dependent way irgen currently handles function calls. Nonetheless, `swift -sil-i hello.swift` works!

There is an apparent case where sema isn't computing the varargs injection function when it should (example 'd'), I'll look at that next.

This is kindof a pain in a few places where the type system
doesn't propagate canonicality. Also, member initializations
are always direct-initializations and so are allowed to use
explicit constructors, which is a hole in our canonicality
tracking. But overall I like the idea of always working
with canonical types.

analysis for patterns.
Major changes:
1. We no longer try to compute the types of functions in the parser.
2. The type of a function always matches the type of the argument patterns.
3. Every FuncDecl now has a corresponding FuncExpr; that FuncExpr might not
have a body, though.
4. We now use a new class "ExprHandle" so that both a pattern and a type
can hold a reference to the same expression.
Hopefully this will be a more reasonable foundation for further changes to
how we compute the types of FuncDecls in generics and for the implementation
of type location information.

level of IR struct type. At first we were emitting two layers
because structs were secretly tuples, and then more recently
we were emitting two layers to avoid having to adjust a bunch
of tests. Just bite the bullet now; it makes the IR a lot
cleaner, and it's never going to be easier.

It does seem silly for this to all be templated, but I couldn't
really see a very elegant solution given how I wanted things to
be genericized.
...interestingly, a ?t.t[] type would have done nicely for some
of this.
Swift SVN r1807
I'm not completely sure this is the representation we want, but it isn't much code to rip out if we decide to represent it some other way.
While I'm in the area, also fix a case where tuple->tuple conversion wasn't working.

first, we weren't registering the cleanup for the temporary
if it needed materialization, and second, we were potentially
double-consuming cleanups associated with the l-value, e.g.
subscript indices.
Swift SVN r1631
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.
Swift SVN r1356
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.

an owner attached. Use this to implement [byref(heap)]. Force
locals to the heap if they've been referenced in a way that requires
this.
Swift SVN r1265
the wrong structure for an l-value. Use a list instead (that is,
something which allows efficient iteration forward through the
collection).
