I think the PR like this should only carry the changes that are provably, uncontroversially, visibly safe. Everything else that has any chance to do semantic changes, should be done in follow-up PRs, IMO.

@shipilev Could you consider accepting the existing `__stdcall` changes in this PR? That seems like the easiest way out of satisfying everyones opinions here..

As I said, I think they are just as safe as any other changes -- the only difference is that it is perhaps not as well-known in the community that they only affect x86.
