Comment (by nbruin):
Patch attached to avoid calling `__init__` in
`Matrix_integer_dense.__cinit__`. This routine chooses to already set
`_parent` (that's easy because that should be a parameter anyway! note
that other classes sometimes get called with `__new__` and `parent=NULL`),
setting base ring is easy. This class also needs `nrows` and `ncols` set
in `__cinit__` already, but unfortunately the only way to get that
information is via an expensive method call on the parent. This is no
worse than happened before, though, because previously this happened in
`__init__`. The present patch should give a very modest speedup, but
mostly it means the code is a little cleaner.
