Blackfin: fix miscompilation in lshrdi3
The code used in the Blackfin lshrdi3 utilizes gcc constructs. However, the structures declared don't line up with the code gcc generates, so under certain optimizations, we get bad code and things crap out in fun random ways. So rather than trying to maintain different gcc definitions ourselves, just use the ones available in gcclib.h.
