The deployment target environment variable is OS-specific, and if you're in a place where you're asking `rustc` for the deployment target, you're likely to also wanna know the environment variable.

Unify `sysroot_target_{bin,lib}dir` handling
Follow-up to rust-lang#131405 (comment) where `sysroot_target_bindir` had to do some dancing because the sysroot ensure logic embedded in `sysroot_target_libdir` returned `$sysroot/$relative_lib/rustlib/$target/lib` and not the `rustlib` parent `$sysroot/$relative_lib/rustlib/`.
This PR pulls out the sysroot ensure logic into a helper, and return `$sysroot/$relative_lib/rustlib/` instead so `sysroot_target_bindir` doesn't have to do parent traversal from the path returned from `sysroot_target_libdir`, and also make them easier to follow in that they are now clearly closely related based on the common target sysroot ensure logic.
…v-var, r=davidtwco Print name of env var in `--print=deployment-target` The deployment target environment variable is OS-specific, and if you're in a place where you're asking `rustc` for the deployment target, you're likely to also wanna know the name of the environment variable. I myself wanted this for some code I'm working on in bootstrap, for example. Behaviour before this PR: ```console $ rustc --print=deployment-target --target=aarch64-apple-darwin deployment_target=11.0 $ rustc --print=deployment-target --target=aarch64-apple-visionos deployment_target=1.0 ``` Behaviour after this PR: ```console $ rustc --print=deployment-target --target=aarch64-apple-darwin MACOSX_DEPLOYMENT_TARGET=11.0 $ rustc --print=deployment-target --target=aarch64-apple-visionos XROS_DEPLOYMENT_TARGET=1.0 ``` My _belief_ is that this option is extremely rarely used in general, and a GitHub search for "rustc print deployment-target" seems to confirm this, it revealed only the following actual pieces of code using this: - https://github.com/PyO3/maturin/blob/b292ef69349f2a56cb8ab1b59fda0be3d3b9f138/src/build_context.rs#L1199-L1220 - https://github.com/rust-lang/cc-rs/blob/daab9244b03e244c4f2511944870d719c443f61f/src/lib.rs#L3422-L3426 `maturin` does `.split('=').last()`, so it will continue to work after this change, but `cc v1.0.84` did `.strip_prefix("deployment_target=")` since [this PR](rust-lang/cc-rs#848), so it would break. That's _probably_ fine though, it was broken in a lot of scenarios anyway, and [got](rust-lang/cc-rs#901) [reverted](rust-lang/cc-rs#943) in `v1.0.85`. So while this is _technically_ a breaking change, I really doubt that anyone is going to observe it, so it's probably fine. ``@BlackHoleFox`` wdyt? ``@rustbot`` label O-apple r? compiler

Deeply normalize when computing implied outlives bounds r? lcnr Unfortunately resolving regions is still slightly scuffed (though in an unrelated way). Specifically, we should be normalizing our param-env outlives when constructing the `OutlivesEnv`; otherwise, these assumptions (https://github.com/rust-lang/rust/blob/dd2837ec5de4301a692e05a7c4475e980af57a57/compiler/rustc_infer/src/infer/outlives/env.rs#L78) are not constructed correctly. Let me know if you want us to track that somewhere.
Add const evaluation error UI test. This closes rust-lang#78834
