undo CL 130240043 / b09f70c301a5

This change broke divmod.go on all arm platforms.

««« original CL description
cmd/gc: change interface representation: only pointers in data word

Note that there are various cleanups that can be made if we keep
this change, but I do not want to start making changes that
depend on this one until the 1.4 cycle closes.

Fixes #8405.
