Auto merge of #115787 - Mark-Simulacrum:stable-next, r=Mark-Simulacrum 1.72.1

[stable] 1.72.1 release

This backports:

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