Cleanup reorder_program.cc
Program::SetParameterOffsetsAndIndex() was being called willy nilly.
Now the invariant is that any function that actually reorders the
program, updates the offsets and indices.
Also the logic around handling EIGEN_SPARSE has been simplified in
anticipation of the block AMD code that is forthcoming.
Last but not the least, num_eliminate_blocks, which is a rather
cryptic name to begin with has been replaced by the more meaningful
size_of_first_elimination_group.
