Roman Gareev 036c08874a Tweak the LICM code to reuse the first sub-loop instead of creating a new one ...

LICM starts with an *empty* AST, and then merges in each sub-loop. While the
add code is appropriate for sub-loop 2 and up, it's utterly unnecessary for
sub-loop 1. If the AST starts off empty, we can just clone/move the contents
of the subloop into the containing AST.
