Avoid invalidating the CFG in `MirPatch`
As a part of this change, we adjust `MirPatch` to not needlessly create unnecessary resume blocks.
r? `@tmiasko`
Always create elided lifetimes, even if inferred.
`PathSource` gives the context in which a path is encountered. The same `PathSource` is used for the full path and the `QSelf` part.
Therefore, we can only rely on `PathSource` to know whether typechecking will be able to infer the lifetimes, not whether we need to insert them at all.

Some `is_useful` cleanups
#98582 was reverted because it was a perf regression.
https://github.com/rust-lang/rust/pull/99806 reintroduces the changes, but this PR picks individual ones that have no regressions.

This is implementing the MCP from rust-lang/compiler-team#493. It is
increasing the minimum requirements of a couple Tier 1 targets, and
others at lower tiers, so this should go through FCP sign-offs for both
`T-compiler` and `T-release`.
The new `linux-gnu` baseline is kernel 3.2 and glibc 2.17. We will also
take that kernel as the minimum floor for _all_ `*-linux-*` targets, so
it may be broadly assumed in the implementation of the standard library.
That does not preclude specific targets from having greater requirements
where it makes sense, like a new arch needing something newer, or a
platform like `linux-android` choosing a newer baseline.

FilesTimes support does not build for ESP-IDF
Commit 1f5d8d49eb broke STD for `target_os = "espidf"`.
In future, we might come up with something more sophisticated (as in using the `utime` function which *is* available on the ESP-IDF platform), but for now we are treating ESP-IDF just like `Redox` in that the new API fails at runtime. Most important for us ATM is to restore successful compilation of STD on our platform.
Set llvm configs when building lld
Several LLVM configs applied when building LLVM should also be applied when building LLD.
For example, without the fix, setting both `llvm.thin-lto=true` and `rust.lld=true` when building on Linux will fail, since we need to manually override the compiler and linker to `clang`, but those will not be used when building LLD, causing link errors.

Prevent ICE for `doc_alias` on match arm, statement, expression
Fixes#99777.
This is a pretty minimal fix that should be safe, since rustdoc doesn't generate documentation for match arms, statements, or expressions. I mentioned in the linked issue that the `doc_alias` target checking should probably be improved to avoid future ICEs, but as a new contributor, I'm not confident enough with the HIR types to make a larger change.
Delay a bug when failed to normalize trait ref during specialization
The error messages still kinda suck here but they don't ICE anymore...
Fixes#45814Fixes#43037
r? types
Use `TraitEngine` in more places that don't specifically need `FulfillmentContext::new_in_snapshot`
Not sure if this change is worthwhile, but couldn't hurt re: chalkification
r? types
relate `closure_substs.parent_substs()` to parent fn in NLL
Fixes#98589
The discrepancy between early- and late-bound lifetimes is because we map early-bound lifetimes into those found in the `closure_substs` while late-bound lifetimes are mapped into liberated free regions:
