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.

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.

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
expressions when no value is required. Teach IR-gen
to emit DotSyntaxBaseIgnoredExprs as known function
references with possibly non-trivial semantics.
Undo the change to getSemanticsProvidingExpr().

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.
Swift SVN r1112
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.
Swift SVN r1111
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.
Swift SVN r1099
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.
