38b7cdf393 Use target instead of machine for mir interpreter integer handling. 
The naming of `machine` only makes sense from a mir interpreter internals perspective, but outside users talk about the `target` platform

interpret: support for per-byte provenance

Also factors the provenance map into its own module.

The third commit does the same for the init mask. I can move it in a separate PR if you prefer.

Fixes https://github.com/rust-lang/miri/issues/2181

0ec3269db8 interpret: rename Tag/PointerTag to Prov/Provenance 
Let's avoid using two different terms for the same thing -- let's just call it "provenance" everywhere.
In Miri, provenance consists of an AllocId and an SbTag (Stacked Borrows tag), which made this even more confusing.

266bab2ab0 make get_relocations private 
This limits access to the relocations data a bit (instead of increasing it just
for the purposes of interning).

97a0b2e2d0 ctfe interning: don't walk allocations that don't need it 
The interning of const allocations visits the mplace looking for references
to intern. Walking big aggregates like big static arrays can be costly,
so we only do it if the allocation we're interning contains references
or interior mutability.

Walking ZSTs was avoided before, and this optimization is now applied
to cases where there are no references/relocations either.

b094116538 interpret: refactor allocation info query 
We now have an infallible function that also tells us which kind of allocation we are talking about.
Also we do longer have to distinguish between data and function allocations for liveness.
