Rollup merge of #100522 - cjgillot:inline-polymorphic-recursion, r=tmiasko
Only check the `DefId` for the recursion check in MIR inliner. The current history check compares `Instance`s, so it cannot detect cases of polymorphic recursion where `Substs` change. This PR makes it so we only compare `DefId`s, ignoring any change in `Substs`. According to https://github.com/rust-lang/rust/pull/100522#issuecomment-1214769757, in practice only very few inlining decisions change. Fixes https://github.com/rust-lang/rust/issues/100476
