c28a8eeb74 Auto merge of #1532 - divergentdave:thread-panic-payload, r=RalfJung 
Move panic payload state from Machine to Thread

This PR moves the panic payload storage from the `Machine` state to per-thread state. Prior to this change, if one thread panicked while another was still unwinding, Miri would fail with `thread 'rustc' panicked at 'the panic runtime should avoid double-panics', src/shims/panic.rs:51:9`. I ran into this issue while prototyping a round-robin scheduler, but it's also reachable with the current scheduler and contrived programs that use blocking API calls to cause thread switching during unwinding. I wrote a test case along those lines for this change.

Support --test/--bin/--lib in cargo-miri

This PR addresses a FIXME in cargo-miri, and filters the targets to be checked when any of the `--bin`, '--test`, or `--lib` flags are passed.

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.
