+ On memory-constrained iOS devices, reduce the rate at which the JS heap grows before a GC to try to keep more memory available for the system

+ The testing I have done shows that this new function is a ~10%
+ progression running JetStream on 1GB iOS devices. I've also tried
+ this on a few > 1GB iOS devices, and the testing shows this is either neutral
+ or a regression. Right now, we'll just enable this for <= 1GB devices
+ since it's a win. In the future, we might want to either look into
+ tweaking these parameters or coming up with a new function for > 1GB
+ devices.
