    Implement -fwarn-missing-pat-syn-sigs · 1883afb2

    This adds a warning when a pattern synonym is not accompanied by a
    signature in the style of `-fwarn-missing-sigs`.
    
    It is turned on by -Wall.
    
    If the user specifies, `-fwarn-missing-exported-signatures` with
    `-fwarn-missing-pat-syn-sigs` then it will only warn when the pattern
    synonym is exported.
