For most types, this is really only useful in the presence of
an unimplemented operation, but for empty types this does come
up quite reasonably.

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.

Set up IRGen to emit SIL code that uses top-level-code global variables. Add -sil-i to a bunch of Interpreter tests that use global variables.

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.

The test changes are that we're setting a class body on
some types that we weren't before. For some of these,
this is okay; for others, it's more questionable, but
ultimately not *harmful*.

Mangling is still a hack, pending a better type AST. Fixed
a bug where arguments passed indirectly were not being destroyed
by the callee (when passed by value). Changed some of the protocol
signatures to use the generic opaque pointer type, making the
types a bit more self-documenting in the IR.

match the actual entrypoints vended by the runtime:
1) there is no swift_slowRawAlloc
2) swift_deallocObject takes two arguments
Also, make all calls to swift_allocObject go through a common
function so that we can easily use optimized entrypoints if the
runtime provides them.
