- Use `object` based test logic instead of processing `nm`
human-readable textual output.
- Try to expand test coverage to not be limited to only linux + x86_64.

Introduce a wrapper for "typed valtrees" and properly check the type before extracting the value
This PR adds a new wrapper type `ty::Value` to replace the tuple `(Ty, ty::ValTree)` and become the new canonical representation of type-level constant values.
The value extraction methods `try_to_bits`/`try_to_bool`/`try_to_target_usize` are moved to this new type. For `try_to_bits` in particular, this avoids some redundant matches on `ty::ConstKind::Value`. Furthermore, these methods and will now properly check the type before extracting the value, which fixes some ICEs.
The name `ty::Value` was chosen to be consistent with `ty::Expr`.
Commit 1 should be non-functional and commit 2 adds the type check.

override build profile for bootstrap tests
Using the release profile for bootstrap self tests puts too much load on the CPU and makes it quite hot on `x test bootstrap` invocation for no good reason. It also makes the compilation take longer than usual (see https://github.com/rust-lang/rust/pull/136048#issuecomment-2616908484). This change turns off the release flag for bootstrap self tests.

Fix a couple Emscripten tests
This fixes a couple Emscripten tests where the correct fix is more or less obvious. A couple UI tests are still broken with this PR:
- `tests/ui/abi/numbers-arithmetic/return-float.rs` (#136197)
- `tests/ui/no_std/no-std-unwind-binary.rs` (haven't debugged yet)
- `tests/ui/test-attrs/test-passed.rs` (haven't debugged this either)

Clean up uses of the unstable `dwarf_version` option
- Consolidate calculation of the effective value.
- Check the target `DebuginfoKind` instead of using `is_like_msvc`.
- Add the tracking issue to the unstable book page for this feature.

Simplify and consolidate the way we handle construct `OutlivesEnvironment` for lexical region resolution
This is best reviewed commit-by-commit. I tried to consolidate the API for lexical region resolution *first*, then change the API when it was finally behind a single surface.

miri: optimize zeroed alloc
When allocating zero-initialized memory in MIR interpretation, rustc allocates zeroed memory, marks it as initialized and then re-zeroes it. Remove the last step.
I don't expect this to have much of an effect on performance normally, but in my case in which I'm creating a large allocation via mmap it gets in the way.
tests: Port `translation` to rmake.rs
Part of #121876.
This PR partially supersedes #129011 and is co-authored with `@Oneirical.`
## Summary
This PR ports `tests/run-make/translation` to rmake.rs. Notable changes from the Makefile version include:
- We now actually fail if the rustc invocations fail... The Makefile did not have `SHELL=/bin/bash -o pipefail`, so all the piped rustc invocations to grep vacuously succeeded, even if the broken ftl test case actually regressed over time and ICEs on current master.
- That test case is converted to assert it fails with a FIXME backlinking to #135817.
- The test coverage is expanded to not ignore windows. Instead, the test now uses symlink capability detection to gate test execution.
- Added some backlinks to relevant tracking issues and the initial translation infra implementation PR.

Merge `PatKind::Path` into `PatKind::Expr`
Follow-up to #134228
We always had a duplication where `Path`s could be represented as `PatKind::Path` or `PatKind::Lit(ExprKind::Path)`. We had to handle both everywhere, and still do after #134228, so I'm removing it now.
