Revert "fix sys.ji build segfault regression"

This reverts commit c3cbd007ae7a6a71dffc50e171a852d4f3ccbbce.
Proper fix for the sys.ji segfault
Don't run GMP tests after cleanall [fixes #1941]
bang: consistently use ! for mutating functions [#907].

This deprecates the non-! versions and prints a warning when they
are used. It doesn't quite close out #907 but comes close. There
are still a few lingering mutators like del_each that we may want
to get rid of or rename somehow.
