Fix indexed-swizzle lvalues in RP codegen.
The previous CL fixed non-lvalue swizzled-index-expressions. This CL
goes further and fixes lvalue swizzled-index-expressions; as such,
the fix from the previous CL is no longer needed.
This is pretty straightforward; we use the existing transform code
to rewrite the swizzle as before. We needed a place to stash the
rewritten expression in the lvalue, so that it wouldn't die before
its associated lvalue, so I added a field for it; not super elegant
but it seems pretty harmless in practice.
