875d914c77 Extract the layout logic out of GenTuple.cpp into a template header. 
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.

f75e305a20 Add ScalarToTupleExpr to represent an implicit conversion from a scalar to a tuple, with or without default arguments. Make Sema and IRGen work with them. 
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.

b3b71178a5 Fix a pair of bugs with partial updates of logical l-values: 
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.

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.

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.

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.

df7ebcd9e8 Introduce the concept of an 'owned address', i.e. an address with 
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.

9038a38ce8 We will need a DiverseStack<T> for cleanups, but a stack is really 
the wrong structure for an l-value.  Use a list instead (that is,
something which allows efficient iteration forward through the
collection).

c7bcadf450 On further reflection and use, the concept of an RValue is not actually 
very useful;  it is much more interesting to divide r-value emission
into "to arguments" and "to memory" models.  To that end, introduce a
new structure for holding an "exploded" r-value.
