The patch. We use sync with no parameters because I could not find a lighter option that would be a proper store fence. I think we could explore the idea of using SYNC_MB for both memoryFence() and storeFence() in the future though.

Could you add a FIXME and comment about SYNC_MB thing?
And in FIXME, adding opened issue URL(in bugzilla) is desireable.

Patch

New version adding a FIXME with a link to https://bugs.webkit.org/show_bug.cgi?id=169984. The FIXME was added to MIPSAssembler::sync() as it is the common denominator for the issue, which likely affects both memoryFence() and storeFence() in the same way.

I think we can safely assume this failure is unrelated with my patch?
