move function indices in IclModule to separate record

'checkError ("no generic instances of "..' in getSymbolType is called

(see example below)
by expanding the type synonym if a type variable is unified with
a type synonym that contains that variable.

:: Parser b a :== (YieldParser b a) -> (ID b) -> b
:: YieldParser b a :== a -> (ID b) -> b
:: ID b :== b

returnP :: a -> Parser b a
returnP x = \yp -> yp x

failP :: Parser b a
failP = \yp fp -> fp

'cannot unify types' on separate lines

remove #defines for UNBOXED_CLOSURES and U_RECORD_SELECTORS
