<pre>Reopening, as the fix was reverted in:
commit 579bab4252d27fec369fca49aab7fda023775307
Author: Hans Wennborg <<a href="mailto:hans@hanshq.net">hans@hanshq.net</a>>
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).
