Auto merge of #108504 - cjgillot:thir-pattern, r=compiler-errors,Nilstrieb
Check pattern refutability on THIR The current `check_match` query is based on HIR, but partially re-lowers HIR into THIR. This PR proposed to use the results of the `thir_body` query to check matches, instead of re-building THIR. Most of the diagnostic changes are spans getting shorter, or commas/semicolons not getting removed. This PR degrades the diagnostic for confusing constants in patterns (`let A = foo()` where `A` resolves to a `const A` somewhere): it does not point ot the definition of `const A` any more.
