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).

c0b44ca98c 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.

a561f949ad Fix project dirs path 
ProjectDirs::from("miri", "miri", "miri")

would get you `miri\miri` on Windows and `miri.miri.miri` on macOS.

I'm assuming here that your intention was to have only a `miri` directory on every OS.
