Rollup merge of #39472 - est31:unadjusted_only_for_win, r=nagisa

Don't use "unadjusted" ABI on non windows platforms

We introduced the unadjusted ABI to work around wrong
(buggy) ABI expectations by LLVM on Windows [1].
Therefore, it should be solely used on Windows and not
on other platforms, like right now is the case.

[1]: see this comment for details https://github.com/rust-lang/rust/pull/38482#issuecomment-269074031
