`for xs: (*m)` binds `m` to a `*T`. Passing it directly to a parameter that wants `T` produced invalid IR that only LLVM's verifier caught, with the opaque 'Call parameter type does not match function signature'. Detect it at the call site and emit a clear error with a fix-it suggesting `m.*`. Add example 215 + expected output as a regression test.

// A by-reference loop capture (`for xs: (*m)`) binds `m` to a `*T`.

// Passing it where a `T` value is expected used to slip through to the

// The compiler now reports it at the call site with a fix-it: write `m.*`.
