See https://rust-lang.zulipchat.com/#narrow/stream/246057-t-cargo/topic/Overriding.20RUSTC_WORKSPACE_WRAPPER.20with.20RUSTC/near/325529313 for the current status - the clippy changes here aren't something we want to land as-is.

// Use a different compiler for build scripts, since there may not yet be a
// libstd for the real compiler to use. However, if Cargo is attempting to
// determine the version of the compiler, the real compiler needs to be
// used. Currently, these two states are differentiated based on whether
// --target and -vV is/isn't passed.

I'll be unavailable for 1 to 2 months to work on it, so I'll mark it as blocked on me.
Concerning the status, it is kinda stuck in a limbo between multiple implementation difficulties. If someone wants to continue this, they can contact me on Zulip and I'll try to answer.

x clippy

thanks to `@asquared31415` `@albertlarsan68` for all their help, most of this pr is their work

note that this also adds x clippy --stage 0 -Awarnings to x86_64-gnu-llvm-15 to make sure it stays working; that won't gate on any clippy warnings, just enforce that clippy doesn't give a hard error. we can't add --stage 1 until clippy fixes its debug assertions not to panic.

note that `x clippy --stage 1` currently breaks when combined with download-rustc.

unlike the previous prs, this doesn't require changes to clippy (it works by using RUSTC_WRAPPER instead), and supports stage 0

closes rust-lang#107628; see also rust-lang#106394, rust-lang#97443. fixes rust-lang#95988. helps with rust-lang#76495.
