Reopening, as the fix was reverted in:

commit 579bab4252d27fec369fca49aab7fda023775307
Author: Hans Wennborg <hans at hanshq.net>
Date:   Thu Sep 22 21:20:53 2016 +0000

    Revert r282168 "GVN-hoist: fix store past load dependence analysis
(PR30216)"

    and also the dependent r282175 "GVN-hoist: do not dereference null
pointers"

    It's causing compiler crashes building Harfbuzz (PR30499).
