Ryan Macnak 829ef92778 [vm] Expand compressed heap to 4GB. 
We originally sized the compressed heap at 2GB to avoid implementing alignment offsets. (When decompression is sign-extension + base, base should be the middle of a 4GB-aligned region.) After 8db0a975c1, the needed alignment offset is zero, and we no longer need to avoid the high bit being set.
