Mangle the signature decl when mangling a thunk. (#7177)
Fixes mangling collisions when two thunks with the same name (eg, `Op`) are created in the same context, which in turn would lead to LLVM verifier failures and miscompiles. To support this, add a new value store to track a little more information about thunks beyond what's in the `Function`.
