BUG: error in broadcast_arrays with as_strided array

[shoyer]

Fixes #6491

nb. this is an awkward solution -- I don't really understand why it works. I suspect it is working around some quirks of the logic for checking if arrays can be made writeable, which is surprisingly convoluted. Note, for example, that base on an array from as_strided is a stride_tricks.DummyArray.

I don't really know what is going on here, but the fix looks reasonable in a complicated sort of way ;)

Thanks Stephan.

Thanks! Fixed the one failure that blocked us from enabling testing against 1.10.1 on TravisCI with Scipy.

Ideally the code could be written in such a way that the writeable flag is
set correctly from the beginning instead of needing to be mutated, but 30
seconds looking at the code certainly does not make it obvious how to do
this :-).
