There's no need to test this more than once. Add a NOHANG
flag which can be used to specify that a subtest can not
be run when hanging. If it's set on either the subtest or
the mode, the -hang test for this combination will not be
generated.
Changes since v1:
- Merge the patch that renamed HANG to NOHANG.
- Rebase after 'reorganize subtests by type'.
- Allow subtests to specify NOHANG too.
