Unrolled build for rust-lang#136526
Rollup merge of rust-lang#136526 - Zalathar:thir-cx, r=Nadrieril mir_build: Rename `thir::cx::Cx` to `ThirBuildCx` and remove `UserAnnotatedTyHelpers` A combination of two loosely-related tweaks that would otherwise conflict with each other: - `Cx` is a pretty unhelpful type name, especially when jumping between THIR-building and MIR-building while trying to make changes to THIR data structures. - The `UserAnnotatedTyHelpers` trait doesn't appear to provide any benefit over a simple helper function, and its `tcx()` method is currently completely unnecessary. No functional change.
