[heap] Throw OOM upon failing to expand a PagedSpace above old gen limits.

[heap] Throw OOM upon failing to expand a PagedSpace above old gen limits.

The AlwaysAllocate scope make it impossible to enforce a DCHECK on the maximum

scope. Returning false here results in OOM.

Unless we change AlwaysAllocate's semantics, I think this is the way to go.
wdyt?
