:sdetar, not sure if this is in your area or not, I suspect arm64 acts differently and amd64 or i386 for large numbers and floating points. If this isn't your area I can look further. My goal is to associate these test failures with tracking bugs, so if there is work in progress lets make this blocking that.

:jmaher, added to Meta bug 1526995 which I am using to track these bugs related to the JS engine. Once we have ARM64 Ion support completed, we can re-validate if these test still fail and need to be fixed.
