give some context in error messages

### Some examples for how different errors look now

Unsupported operation:
```
error: unsupported operation: Miri does not support threading
  --> /home/r/.rustup/toolchains/miri/lib/rustlib/src/rust/src/libstd/sys/unix/thread.rs:68:19
   |
68 |         let ret = libc::pthread_create(&mut native, &attr, thread_start, &*p as *const _ as *mut _);
   |                   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Miri does not support threading
   |
   = help: this is likely not a bug in the program; it indicates that the program performed an operation that the interpreter does not support
```
Unsupported operation that works without isolation:
```
error: unsupported operation: `clock_gettime` not available when isolation is enabled
   --> /home/r/.rustup/toolchains/miri/lib/rustlib/src/rust/src/libstd/sys/unix/time.rs:349:22
    |
349 |         cvt(unsafe { libc::clock_gettime(clock, &mut t.t) }).unwrap();
    |                      ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ `clock_gettime` not available when isolation is enabled
    |
    = help: pass the flag `-Zmiri-disable-isolation` to disable isolation
```
Program abort:
```
error: program stopped: the evaluated program aborted execution
   --> /home/r/.rustup/toolchains/miri/lib/rustlib/src/rust/src/libstd/panicking.rs:530:18
    |
530 |         unsafe { intrinsics::abort() }
    |                  ^^^^^^^^^^^^^^^^^^^ the evaluated program aborted execution
    |
```
UB:
```
error: Undefined Behavior: type validation failed: encountered 2, but expected a boolean
 --> tests/compile-fail/validity/invalid_bool.rs:2:23
  |
2 |     let _b = unsafe { std::mem::transmute::<u8, bool>(2) }; //~ ERROR encountered 2, but expected a boolean
  |                       ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ type validation failed: encountered 2, but expected a boolean
  |
  = help: this indicates a bug in the program: it performed an invalid operation, and caused Undefined Behavior
```
Experimental UB:
```
error: Undefined Behavior: not granting access to tag <1562> because incompatible item is protected: [Unique for <1567> (call 1189)]
  --> tests/compile-fail/stacked_borrows/aliasing_mut1.rs:3:1
   |
3  | pub fn safe(_x: &mut i32, _y: &mut i32) {} //~ ERROR protect
   | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ not granting access to tag <1562> because incompatible item is protected: [Unique for <1567> (call 1189)]
   |
   = help: this indicates a potential bug in the program: it performed an invalid operation, but the rules it violated are still experimental
```

@CAD97 [proposed](https://github.com/rust-lang/miri/issues/1059#issuecomment-601217992) trying to get a better error for failed panics on Windows.

ee71b2e140 Auto merge of #1243 - RalfJung:instant, r=RalfJung
implement Instant::now

For now, this is Linux-only.

Unlike `SystemTime`, we cannot convert `Instant` to something absolute via an epoch. But that's okay, that clock is relative anyway, so we just make up our own time anchor when interpretation starts.
