de07843bf3 If a node that defines a physical register that is expensive to copy. The 
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.

f536e2f41e - Added a few target hooks to generate load / store instructions from / to any 
address (not just from / to frameindexes).
- Added target hooks to unfold load / store instructions / SDNodes into separate
load, data processing, store instructions / SDNodes.
