[patch] Avoid invalid DMA sizes for vmul

[Jules Bergmann]

This patch fixes the cleanup code to avoid DMA sizes that aren't a 
multiple of 16.  This fixes test failures for coverage_binary.  It also 
adds a new regression test that sweeps through vmul sizes from 1 to 128.

Don, is this ok to commit?  Is there a better place than bindings.hpp to 
put the GRANULARITY macro and is_dma_size_ok() function?

I'm currently running a regression now to see how this works out.
