@vnkozlov  We definitely need the CPU features check to go in before we push this PR. I asked @ashu-mehra to make a start on that.

We also need to upstream the changes to use the AOTConstantsRegion before pushing this PR. I'll raise a PR for that.

I have added the fixes for the klass and oop management to this PR. I think that's appropriate because it is only AOT code generated via this PR that is calling the relevant macroassembler methods.
