09b0a8a813 Auto merge of #1022 - christianpoveda:fix-fd-access, r=RalfJung 
Fix unchecked memory access for files

This PR takes care of two problems:

- It uses `Memory::(read|write)_bytes` to guarantee that memory accesses are checked (Fixes: https://github.com/rust-lang/miri/issues/1007)
- It removes the `(get|remove)_handle_and` methods which were a little bit cumbersome to use. In particular `remove_handle_and`, because we were using it to avoid borrowing issues before the `Evaluator::memory` field was public.

More tests for dyn trait (in particular, unsized receivers)

So far we only tested them indirectly through `dyn FnOnce`; this also adds some self-contained tests from the rustc test suite.

error code E0080 is no longer printed with MIRI error message

Thanks to help from @bjorn3, @RalfJung, and @oli-obk on issue #1035 , I fixed the miri code so that error code **E0080** is no longer printed out for MIRI evaluation errors. I tested my code in my Linux machine as below.
![image](https://user-images.githubusercontent.com/10286488/68264744-e71e6c80-0017-11ea-9028-f83e19164ea2.png)

Remaining concern is whether the variable name `new_tcx` which I used is misleading or not.

4ddc37df7a Auto merge of #1031 - RalfJung:ptr-offset, r=RalfJung 
Refactor ptr_offset_inbounds

I finally found a way to write this using basically just `check_ptr_access` while handling all cases (integers and pointers, offset 0 or not) correctly. This changes behavior for NULL ptrs, but I think the change is for the better.

Depends on https://github.com/rust-lang/rust/pull/66081.
