Fixes rust-lang#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.
