We already did this, but missed a few cases due to the way arguments are elaborated. So now, when checking an LHS, we don't allow LHS argument types to be inferred from the pattern, but rather they must be inferred from elsewhere. To do this, we keep track of the constraints which would be solved when inferring the type, and make sure they don't solve any new metavariables. Fixes #1510, and also now gets the error location right as a bonus!
