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.
