    Add new debugging flag -dinline-check
    
    This flag reports a summary of the inlining decision for identifiers
    prefixed by the flag's argument.
    
    For example, `-dinline-check foo` will report why definitions whose
    prefix is `foo` are inlined or not.
    
    Previously the only way to get this information was to pass a
    combination of `-dverbose-core2core` and `-ddump-inlinings`.
    
    This combination led to a log of 12 million lines in a module of about
    200 lines I recently had to apply it to. This flag provides a much more
    direct way to find the occurence you care about.
