93f5892962 Auto merge of #815 - RalfJung:memory-audit, r=RalfJung 
don't call Memory::get without checking the pointer first

Also avoid Memory::get if we just need to know align/size.

I audited all uses of `alloc_id`; the rest should be fine (and we can kill a bunch of them once https://github.com/rust-lang/rust/pull/62257 lands).

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.)

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.
