Revert "Use MADV_FREE to reclaim pages of freed regions"
This reverts commit 315f1b21a51a67e5d9c9ec3a04f1887931061e10.
Reason for revert: Regression in PSS (b/155678984). Also MPTS test report a low hit ratio (20%), which doesn't justify the change, at least in the current format. A workaround will be to bring back marking pages back and only madv_free first few regions which are expected to be allocated soon. The rest of the regions should probably be reclaimed with MADV_DONTNEED. Also, for a GC happening when the app is in background should probably reclaim all regions with MADV_DONTNEED.
