[PyCUDA] GPUArray does not allow Python longs as shapes

[Irwin Zaid]

Hi all,

I just found (in my opinion) what may be a bug in GPUArray. Python 2.x 
has both ints and longs, and some functions (including some in numpy) 
may return either depending on the input.

GPUArray, however, only likes ints as shape parameters. This seems to be 
resolvable by changing line 159 in gpuarray.py from "assert 
isinstance(shape, int)" to "assert isinstance(shape, (int, long))".

Cheers,

Irwin
