Fix in methods 'reinterpret' and 'reshape' for sparse matrices.

Calling these methods on sparse matrices would result in corruption
of the original matrix, due to an accidental sharing of the 'rowval'
field.  This is now prevented by copying the field.
Changed `copy` to `similar` of previous fix, and added test case.
Changed `reshape` of a sparse matrix

Nonzero elements now copied rather than shared, to prevent
accidental corruption when inserting new elements.
Added a lacking `copy` command to proposed test case.

base/operators.jl: remove harmful (incorrect) fallback for cmp.

This was causing cmp(Uint128,Uint128) to give wrong answers. The
other more general fallback that already exists is better.
