Loop distribution fix for SCC detection
The following adjusts data_dep_in_cycle_p to properly consider the
whole loop nest when looking for data dep cycles and exempting
zero-distance DDRs instead of just the outermost loop.
* tree-loop-distribution.cc (loop_distribution::data_dep_in_cycle_p):
Consider all loops in the nest when looking for
lambda_vector_zerop.
