[patch] Fix pointer comparison

[Jules Bergmann]

The pointer equality check for an in-place transpose will cause a 
compilation error for assignments between different value types (such as 
in view.cpp).

This patch fixes that by introducing an 'is_same_ptr' that can compare 
pointers of different types.

It also includes a simple unit-test for in-place transpose.

Ok to apply?
