[patch] Handle unaligned Fft, Fftm; Split view_functions test.

[Jules Bergmann]

This patch fixes the Cbe Fft and Fftm backends to request have 16-byte 
alignment, which is necessary for DMA.  It also adds regression tests 
for unaligned Fft and Fftm.

It splits the view_functions test into three smaller tests.  Compiling 
view_functions with optimization turned on was being killed by the 
process killer on snipes.

Patch applied.
