Optimize dataflow-const-prop place-tracking infra

Optimization opportunities found while investigating https://github.com/rust-lang/rust/pull/110719

Computing places breadth-first ensures that we create short projections before deep projections, since the former are more likely to be propagated.

The most relevant is the pre-computation of flooded places. Callgrind showed `flood_*` methods and especially `preorder_preinvoke` were especially hot. This PR attempts to pre-compute the set of `ValueIndex` that `preorder_invoke` would visit.

Using this information, we make some `PlaceIndex` inaccessible when they contain no `ValueIndex`, allowing to skip computations for those places.

15aa7fad7e Simplify the implementation of iterators over slices of ZSTs 
Currently, slice iterators over ZSTs store `end = start.wrapping_byte_add(len)`.

That's slightly convenient for `is_empty`, but kinda annoying for pretty much everything else -- see bugs like 42789, for example.

This PR instead changes it to just `end = ptr::invalid(len)` instead.

That's easier to think about (IMHO, at least) as well as easier to represent.

d2ea42fad3 Auto merge of #2879 - saethlin:measureme, r=RalfJung 
Include the current Crate name in the measureme output name

See https://rust-lang.zulipchat.com/#narrow/stream/182449-t-compiler.2Fhelp/topic/measureme.20flamegraph.20panics/near/356367013
cc `@andjo403`

Currently, attempting to use `MIRIFLAGS=-Zmiri-measureme=miri cargo miri test` on a crate with multiple test targets (which is very common) will produce a corrupted measureme output file, because the various interpreter processes will stomp each other's output.

This change does not entirely prevent this, but the various test targets seem to always have different crate names, so if nothing else this will make the broken measureme files much harder to encounter by accident, while also making it clear what they are all for.

Don't force include Windows goop when documenting

Why do we need to include all the windows bits on non-windows platforms? Let's try not doing that.

Possible alternative to #111394, if it works.
