This is handled by our code: in relevant case also other functions
are missing, we detect this and revert to generic method.
Concerning performance: in older sbcl 'make-array' for specialized
arrays had really bad performance, so our code was really important.
In newer sbcl 'make-array' is faster, so using it is no so bad...
