This fixes a corner case during young generation evacuation:
1) Sweeping is in progress, but all pages are swept.
2) The main thread has acquired all swept pages.
3) A compaction space cannot get any swept page and has to allocate a
   new page.

This reduces memory usage of ArrayLiteralInitialSpreadLargeDoubleHoley
microbenchmark by 2x.
