code review 5662043: gc: delete old unsafe functions

gc: delete old unsafe functions

Also update build to be able to run mkbuiltin again.
The export form has changed a little, so builtin.c has
more diffs than unsafe.go.

In CL 5650069, I just edited the documentation, a rarely
successful method of change.
