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.

Rollup merge of #110673 - compiler-errors:alias-bounds-2, r=lcnr
Make alias bounds sound in the new solver (take 2)

Make alias bounds sound in the new solver (in a way that does not require coinduction) by only considering them for projection types whose corresponding trait refs come from a param-env candidate.

That is, given `<T as Trait>::Assoc: Bound`, we only *really* need to consider the alias bound if `T: Trait` is satisfied via a param-env candidate. If it's instead satisfied, e.g., via an user provided impl candidate or a , then that impl should have a concrete type to which we could otherwise normalize `<T as Trait>::Assoc`, and that concrete type is then responsible to prove the `Bound` on it.

Similar consideration is given to opaque types, since we only need to consider alias bounds if we're *not* in reveal-all mode, since similarly we'd be able to reveal the opaque types and prove any bounds that way.

This does not remove that hacky "eager projection replacement" logic from object bounds, which are somewhat like alias bounds. But removing this eager normalization behavior (added in #108333) would require full coinduction to be enabled. Compare to #110628, which does remove this object-bound custom logic but requires coinduction to be sound.

63fc57b98e Auto merge of #106560 - bjorn3:support_staticlib_dylib_linking, r=pnkfelix
Support linking to rust dylib with --crate-type staticlib

This allows for example dynamically linking libstd, while statically linking the user crate into an executable or C dynamic library. For this two unstable flags (`-Z staticlib-allow-rdylib-deps` and `-Z staticlib-prefer-dynamic`) are introduced. Without the former you get an error. The latter is the equivalent to `-C prefer-dynamic` for the staticlib crate type to indicate that dynamically linking is preferred when both options are available, like for libstd. Care must be taken to ensure that no crate ends up being merged into two distinct staticlibs that are linked together. Doing so will cause a linker error at best and undefined behavior at worst. In addition two distinct staticlibs compiled by different rustc may not be combined under any circumstances due to some rustc private symbols not being mangled.

To successfully link a staticlib, `--print native-static-libs` can be used while compiling to ask rustc for the linker flags necessary when linking the staticlib. This is an existing flag which previously only listed native libraries. It has been extended to list rust dylibs too. Trying to locate libstd yourself to link against it is not supported and may break if for example the libstd of multiple rustc versions are put in the same directory.

For an example on how to use this see the `src/test/run-make-fulldeps/staticlib-dylib-linkage/` test.
