RTS timer gets turned off when using +RTS -I0
This bug was reported to me by hvr
on IRC. I fixed it in GHC yesterday, but we still need a test, and we could potentially merge this to the 7.4 and 7.6 branches:

Fix a bug in the handling of recent_activity
The problem occurred when the idle GC was turned off with +RTS -I0.
Then the scheduler would go into the state ACTIVITY_DONE_GC directly
without doing a GC, and a subsequent GC would put it back to
ACTIVITY_YES but without turning the timer back on. Instead if the GC
finds the state is ACTIVITY_DONE_GC it should leave it there.
