Propagate the return code from the start lang item 
Fixes #1064

This ensures that we set the error code properly when a panic unwinds
past `main`.

I'm not sure what the best way to write a test for this is

Support unwinding after a panic 
Fixes #658

This commit adds support for unwinding after a panic. It requires a
companion rustc PR to be merged, in order for the necessary hooks to
work properly.

Currently implemented:
* Selecting between unwind/abort mode based on the rustc Session
* Properly popping off stack frames, unwinding back the caller
* Running 'unwind' blocks in Mir terminators

Not yet implemented:
* 'Abort' terminators

This PR was getting fairly large, so I decided to open it for review without
implementing 'Abort' terminator support. This could either be added on
to this PR, or merged separately.

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.

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.
