commit f753cf11eb9e310b54b08d9a1ea1d11540d8eb69

    Allow deferred type error warnings to be suppressed
    
    Adds a flag -fwarn-deferred-type-errors similar to -fwarn-typed-holes.
    Changes the boolean flag of -fdefer-type-errors to a 3-state flag
    similar to the one used by -fdefer-typed-holes/-fwarn-typed-holes.
    
    Test Plan: Since only the absence of deferred type error warnings when
    -fno-warn-deferred-type-errors is passed has to be tested, I duplicated
    a test case checking -fdefer-type-errors and adjusted it accordingly.
