Properly suppress derived type error messages

Previously, the typechecker suppressed many but not all errors,
by suppressing errors where the actual type was either ty_err, or
a function type whose result was ty_err. Added a has_ty_err flag
to the type flags so as to suppress errors for any types involving
ty_err.

build.

This is very helpful for SDL, as SDL wants you to define a function named
