legendecas bbd800c6e3 [heap] Fix incorrect from space committed size 
NewSpace page operations like RemovePage, PrependPage, and
EnsureCurrentCapacity should account for committed page size.

This may happen when a page was promoted from the new space to
old space on mark-compact.

Also, add DCHECKs on Commit and Uncommit to ensure the final
committed page size is the same as the current state.
