Fix `unused_must_use` inside `Box`

After https://github.com/rust-lang/rust/pull/62228, this will be linted against (and causes the test to fail). (This blocks https://github.com/rust-lang/rust/pull/62228.)

048b00d20f Auto merge of #805 - RalfJung:shims, r=RalfJung 
move shims (foreign items and intrinsics) into submodule

This is in preparation for dlsym support, where there will b a third "kind" of shim.

And maybe some day we find a good way to split those long files...

tweak inttoptr allocation behavior

- Make `align_addr` not offset by `align` for no reason.
- Add some random slack between allocations to give them the chance to not be aligned.

some lib.rs refactoring

Taken out of https://github.com/rust-lang/miri/pull/799 so that we can land it now and resolve merge conflicts instead of dragging them along.

Splits lib.rs into machine.rs for the machine state and trait impl, and eval.rs for the main evaluator loop and setting up the initial stack frame.

Show usage if run without arguments

Before, running `./miri` without arguments gave
'./miri: 92: shift: can't shift that many' if run with /bin/sh,
or no output at all when run with bash (because of the `set -e` at the top).

Although that gives some indication of the error, it's not as helpful as
showing the usage.
