cpu: Add force_generic_code flag to cpu_info struct

Browse source 
The remapper and channel mixing code have (faster) specialized and (slower)
generic code certain code path. The flag force_generic_code can be set to
force the generic code path which is useful for testing. Code duplication
(such as in mix-special-test) can be avoided, cleanup patches follow.
