Implemented acclerator-optimized versions of localCopyRegion and insertSliceLocal to speed up padding

Browse Source 
Fixed const correctness on PaddedCell methods
Fixed compile issues on Crusher
Added timing breakdowns for PaddedCell::Expand and the padded implementations of the staples, visible under --log Performance
Optimized kernel for StaplePadded
Test_iwasaki_action_newstaple now repeats the calculation 10 times and reports average timings
