whitelist platforms where panicking should work

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

Could you test if this works for you?

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.

6b56aefa0b Auto merge of #1239 - elichai:2020-03-abort-intrinsics, r=RalfJung 
Abort instead of panic on asserting intrinsics

This fixes #1222
replacing the panic with an abort and a corresponding message.
the stack trace is already printed, this just adds an optional message the caller can pass, and I just pass the same message we passed to the panic but now to the abort instead.

5e7fd2b44d Auto merge of #1238 - RalfJung:mir-opt-test, r=oli-obk 
move repeated run of test suite (without and with MIR optimizations) out of compiletest

Just like we already pass the target architecture to our compiletest wrapper via `MIRI_TEST_TARGET` (and then have CI run compiletest with different values for that env var), we now do the same for running the tests with and without MIR optimizations.

This has the advantage of speeding up local `./miri test`, where in the vast majority of cases running tests both with and without optimizations is just a waste of time.
