2d6d73fafe Auto merge of #1517 - RalfJung:align-test, r=RalfJung 
forgot to add alignment test loop in one test

As expected, checking the physical integer address made alignment tests fragile, and I forgot to add the retry loop for this one.

Remove lifetime from FileDescriptor trait

Also:

- Add note about flush being unnecessary when writing to stderr

accept some post-monomorphization errors

For https://github.com/rust-lang/miri/issues/1382, we also need to allow `ReferencedConstant` post-monomorphization errors. The other post-monomorphization errors should still be impossible to trigger in Miri. The fix is not complete though without https://github.com/rust-lang/rust/pull/75339.

Add `impl FileDescriptor` for stdin, stdout, stderr

- Use `FileDescriptor::read` for stdin reads
- Use `FileDescriptor::write` for stdout/err writes

Add FileDescriptor trait to abstract fn's on File's and Stdin,Stdout,Stderr

Related issue: #1486

Instead of mapping FDs to `FileHandle`, map them to a `FileDescriptor` trait object. The goal is to eventually have both `FileHandle` as well as `Stdin`, `Stdout` and `Stderr` implement this trait so that syscalls involving FDs can handle both `File`s as well as the standard IO streams.

This PR adds the `FileDescriptor` trait and an `impl` for `FileHandle`. I'll open a separate PR for implementing the trait for the standard IO streams.

3386f12eca Wrap io::Result from FileDescriptor::{read,write,seek} in InterpResult 
The outer InterpResult will be used to indicate that a fn is not
implemented for a struct(eg. `write` for Stdin).

The inner io::Result is just the result from the read/write/seek.
