Validate args are correct for `UnevaluatedConst`, `ExistentialTraitRef`/`ExistentialProjection` For the `Existential*` ones, we have to do some adjustment to the args list to deal with the missing `Self` type, so we introduce a `debug_assert_existential_args_compatible` function to the interner as well.
The rustc_sanitizers
crate contains the source code for providing support for
the sanitizers to the Rust compiler.
