Reduce suspend check threshold
Reduce suspend check threshold

The Quick compiler uses a dedicated count-down register (r4)
to reduce the cost of checking for suspend requests.  In order
to reduce suspend latency, this CL reduces the countdown value
from 1000 to 96.

See bug 17953517 for more discussion.
