fschneider@chromium.org 7d8e6c929d Enable GVN for polymorphic loads by not expanding them at the HIR level. 
This change adds a new IR instruction for polymorphic loads. It performs
map compares and loads in one IR instruction instead of splitting each
load into a graph of map-compares and field loads.
 
The advantage is a smaller IR and less basic blocks, plus it allows to
do GVN on polymorphic loads.
