rustc-1.84.1

[Bruce Dubbs]

New point version.

[Xi Ruoyao]

1.84.1 resolves a few regressions introduced in 1.84.0:

• Fix ICE 132920 in duplicate-crate diagnostics.
• Fix errors for overlapping impls in incremental rebuilds.
• Fix slow compilation related to the next-generation trait solver.
• Fix debuginfo when LLVM's location discriminator value limit is exceeded.

It also includes several fixes for those building Rust from source:

• Only try to distribute llvm-objcopy if LLVM tools are enabled.
• Add Profile Override for Non-Git Sources.
• Resolve symlinks of LLVM tool binaries before copying them.
• Make it possible to use ci-rustc on tarball sources.

Replying to Xi Ruoyao:

• Add Profile Override for Non-Git Sources.

This change has made profile = 'dist' the default. As we've discussed in #20897 it contains some things we don't want :(.

It seems not true.

Fixed at r12.2-1166-gff585626ab. I've observed no positive nor negative effect of the change mentioned above, thus it seems just ineffective. How to (and should they) make it effective is the business of the upstream, not us.
