da940eb91f Auto merge of #1354 - divergentdave:dump-alloc-on-undef-read, r=RalfJung 
Print hex dump of alloc on reading undef bytes

Here's a small addition I made locally to the UB diagnostics, in case you're interested in it. This PR calls `dump_alloc()` on the relevant allocation if Miri fails on UB due to reading undefined bytes. This came in handy when diagnosing such an issue in a large program using unsafe Rust, in part because it wasn't deterministic enough to use `-Zmiri-track-alloc-id=`. If you'd like to put this behind another -Z flag, let me know.

45113eb6a4 Auto merge of #1325 - RalfJung:float_to_int_unchecked, r=RalfJung 
implement float_to_int_unchecked

@hanna-kruppe would be great if you could have a look at this.

`float.rs` tests legal casts. `test_cast` checks that both `as` casts and unchecked casts work (i.e., these are not saturating). The `compile-fail` tests should ensure that illegal casts via the intrinsic are detected as such.

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.

Implement non-deterministc mode 
Part of #653

This allows us to properly implement getrandom(),
which unlocks the default HashMap type (e.g. HashMap<K, V>)
with RandomState)

This commit adds a new '-Zmiri-seed=<seed>' option. When present,
this option takes a 64-bit hex value, which is used as the seed
to an internal PRNG. This PRNG is used to implement the 'getrandom()'
syscall.

When '-Zmiri-seed' is not passed, 'getrandom()' will be disabled.
