This is achieved by filtering perlasm output through arm-xlate.pl. But note
that it's done only if "flavour" argument is not 'void'. As 'void' is
default value for other ARM targets, permasm output is not actually
filtered on previously validated platforms.

Modest improvement coefficients mean that code already had some
parallelism and there was not very much room for improvement. Special
thanks to Ted Krovetz for benchmarking the code with such patience.
