volk: make sure the alignment call for a block passes at least 1.
For machines with an alignment of 1, the blocks were truncating the aligment to 0. This makes sure that it gets set to a minimum of 1.
Removed whitespace and added dtools/bin/remove-whitespace as a tool to do this in the future.
The sed script was provided by Moritz Fischer.
core: moving multiply_cc and multiply_const_cc out of gengen and into general so they can make use of volk calls.
QA code now explicitly tests the cc versions of these blocks.
