871005 - Add a pref for GC decommit threshold

Status: RESOLVED FIXED

(Core :: JavaScript Engine, defect)

Right now it's fixed at 32MB, and we want to make it 1MB on mobile. We changed the compile-time constant on the b2g18 branch, but we need a real pref to check in to mozilla-central.

I think Android would also benefit from a smaller number.

Sorry I let this sit so long.
