Improve return code propagation. 
Don't explicitly exit if we reported an evaluation error

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.

c0b44ca98c tweak inttoptr allocation behavior 
- Make `align_addr` not offset by `align` for no reason.
- Add some random slack between allocations to give them the chance to not be aligned.
