Subject: [X86] Move Atomic binops to use WriteALURMW schedule class
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b80d27a916988f45fa851f23dbb0cdb5649916f7;p=platform%2Fupstream%2Fllvm.git

[X86] Move Atomic binops to use WriteALURMW schedule class

These were being tagged as <WriteALULd, WriteRMW> instead of properly using the RMW sequence
