Avoid #'delq in core code, for the sake of style and a (very
slightly) smaller binary.

1. Replace (delq nil (mapcar ....)) with analogous (mapcan ...)
forms; this is in non-dumped files, it was done previously in
dumped files.
2. Replace (delq FOO (copy-sequence BAR)) with (remove* FOO BAR),
where #'eq and #'eql are equivalent
3. Replace (delq FOO BAR) with (delete* FOO BAR), where FOO is not
a non-fixnum number. Saves a little space in the dumped file
(since the compiler macro adds :test #'eq to the delete* call if
it's not clear that FOO is not a non-fixnum number).
