For `broken-pipe-no-ice` until std `anonymous_pipe` stabilizes.

Currently it relies on special treatment of `kw::Empty`, which is really
easy to get wrong. This commit makes the special case clearer in the
type system by using `Option`. It's a bit clumsy, but the synthetic name
handling itself is a bit clumsy; better to make it explicit than sneak
it in.
Fixes #133426.

We register the provider when we start the server. It confused me why I set the option and it didn't work, so probably better to have it hint people.

thaliaarchi:use-prelude-size-of.boostrap-compiletest, r=jieyouxu
bootstrap and compiletest: Use `size_of_val` from the prelude instead of imported
Use `std::mem::size_of_val` from the prelude instead of importing or qualifying it.
This function was added to all preludes in Rust 1.80.

Specifically, when a rename of a local will change some code that refers it to refer another local, or some code that refer another local to refer to it.
We do it by introducing a dummy edit with an annotation. I'm not a fond of this approach, but I don't think LSP has a better way.

This is required to format evaluated consts, because we need trait env, and it needs the crate (currently it uses the last crate in topological order, which is wrong, the next commit will fix that).

miri native-call support: all previously exposed provenance is accessible to the callee
When Miri invokes a native C function, the memory C can access needs to be "prepared": to avoid false positives, we need to consider all that memory initialized, and we need to consider it to have arbitrary provenance. So far we did this for all pointers passed to C, but not for pointers that were exposed already before the native call. This PR adjusts the logic so that we now "prepare" all memory that has ever been exposed.
This fixes cases such as:
- cast a pointer to integer, send that integer to C, and access the memory there (`test_pass_ptr_as_int`)
- send a pointer to some memory to C, which stores it somewhere; then in Rust store another pointer in that memory, and access that via C (`test_pass_ptr_via_previously_shared_mem`)

Pattern types: Avoid having to handle an Option for range ends in the type system or the HIR
Instead,
1. during hir_ty_lowering, we now generate constants for the min/max when the range doesn't have a start/end specified.
2. in a later commit we generate those constants during ast lowering, simplifying everything further by not having to handle the range end inclusivity anymore in the type system (and thus avoiding any issues of `0..5` being different from `0..=4`
I think it makes all the type system code simpler, and the cost of the extra `ConstKind::Value` processing seems negligible.
