This is being discussed on zulip and I don't think it is worth it to hold back this PR

[stable] 1.72.1 release

This backports:

*  Remove assert that checks type equality rust-lang#115215
*  implied bounds: do not ICE on unconstrained region vars rust-lang#115559
*  rustdoc: correctly deal with self ty params when eliding default object lifetimes rust-lang#115276
*  Stop emitting non-power-of-two vectors in (non-portable-SIMD) codegen rust-lang#115236
*  Normalize before checking if local is freeze in deduced_param_attrs rust-lang#114948

Some cherry-picks required merge conflict resolution, we'll see if I got it right based on CI (rustdoc fix and LLVM codegen test).
