webrev: http://cr.openjdk.java.net/~jcm/8213825/webrev.00/index.html

Bug & Fix Desc:

if markword load has sfpt as control i/p(i.e synchronizations near a 
safepoint), it skips sfpt assuming sfptOp wouldn't write to markword memory
fix: not to skip sfpt for markword loads.

tests: hs-tier1-5,  hs-precheckin-comp
