scheduler will try a number of tricks in order to avoid generating the
copies. This may not be possible in case the node produces a chain value
that prevent movement. Try unfolding the load from the node before to allow
it to be moved / cloned.

- Added target hooks to unfold load / store instructions / SDNodes into separate
load, data processing, store instructions / SDNodes.
