When devirtualizing the conversion to a virtual base subobject,
...
don't explode if the offset we get is zero. This can happen if
you have an empty virtual base class.
While I'm at it, remove an unnecessary block from the IR-generation
of the null-check, mark the eventual GEP as inbounds, and generally
prettify.

Move test, so it actually tests what it is supposed to (given that we don't have an AST verifier).

Be sure to emit lvalue-to-rvalue casts for loads from x-values.
...
Doing this happens to disrupt the pattern that ARC was looking for
for move optimizations, so we need to fix that simultaneously.

When producing IR for a lvalue-to-rvalue cast *as an lvalue*, only
...
non-class prvalues actually require the realization of a
temporary. For everything else, we already have an lvalue (or class
prvalue) in the subexpression.
Note: we're missing some move elision in this case. I'll tackle that next.
