Revert^5 "Disable write-barrier elimination pass"

This reverts commit 31b949bc4a76e5c6d00a8e18c346f123b5321a1c.

Reason for revert:
PS1 is reland as-is
PS2 has two fixes:
  * Missed poisoning heap references in a code path
  * Removed incorrect DCHECK

Change-Id: I81b317ddc704dbd8a173f5d5c624dbc69e2d9e60
Test: art/test/testrunner/testrunner.py --host --64 --optimizing -b
Test: art/test/testrunner/testrunner.py --target --64 --optimizing -b
      Both commnands with `export ART_HEAP_POISONING=true`
