5a5e2489c5 Reduce pub exposure. 
A lot of errors don't need to be visible outside the crate, and some
other things as well.

e3f9b2f27c Rollup merge of #122080 - Zalathar:drop-tree, r=oli-obk 
Clarity improvements to `DropTree`

These changes are based on some points of confusion I had when initially trying to understand this code.

The only “functional” change is an additional assertion in `<ExitScopes as DropTreeBuilder>::link_entry_point`, checking that the dummy terminator is `TerminatorKind::UnwindResume` as expected.

570376c496 Don't pass a break scope to Builder::break_for_else 
This method would previously take a target scope, and then verify that it
was equal to the scope on top of the if-then scope stack.

In practice, this means that callers have to go out of their way to pass around
redundant scope information that's already on the if-then stack.

So it's easier to just retrieve the correct scope directly from the if-then
stack, and simplify the other code that was passing it around.

5ba70bd3ec Replace tuples in DropTree with named structs 
This allows us to use real field names instead of tuple element numbers.

Renaming `previous_drops` to `existing_drops_map` clarifies that "previous" was
unrelated to drop order.

fbdac30427 Rename DropTree::add_entry to add_entry_point 
This clarifies that we're adding an "entry point", not just adding an "entry"
of some kind.

98166358a9 coverage: Use SpanMarker to mark continue expressions.

7060fc8327 Replace no_ord_impl with orderable. 
Similar to the previous commit, this replaces `newtype_index`'s opt-out
`no_ord_impl` attribute with the opt-in `orderable` attribute.

a2ee7592d6 Use &IndexSlice instead of &IndexVec where possible 
All the same reasons as for `[T]`: more general, less pointer chasing, and `&mut IndexSlice` emphasizes that it doesn't change *length*.

b3a47d9b6b Desugars drop and replace at MIR build 
This commit desugars the drop and replace deriving from an
assignment at MIR build, avoiding the construction of the
DropAndReplace terminator (which will be removed in a followign PR)

In order to retain the same error messages for replaces a new
DesugaringKind::Replace variant is introduced.

8bfd6450c7 A few small cleanups for newtype_index 
Remove the `..` from the body, only a few invocations used it and it's
inconsistent with rust syntax.

Use `;` instead of `,` between consts. As the Rust syntax gods inteded.
