No join-point from an INLINE function with wrong arity
The main payload of this patch is NOT to make a join-point from a function with an INLINE pragma and the wrong arity; see Note [Join points and INLINE pragmas] in CoreOpt. This is what caused Trac #13413. But we must do the exact same thing in simpleOptExpr, which drove me to the following refactoring: * Move simpleOptExpr and simpleOptPgm from CoreSubst to a new module CoreOpt along with a few others (exprIsConApp_maybe, pushCoArg, etc) This eliminates a module loop altogether (delete CoreArity.hs-boot), and stops CoreSubst getting too huge. * Rename Simplify.matchOrConvertToJoinPoint to joinPointBinding_maybe Move it to the new CoreOpt Use it in simpleOptExpr as well as in Simplify * Define CoreArity.joinRhsArity and use it
