OMC does not detect local non-component elements

[Martin Sjölund]

The following should generate an error instead of silently failing.

{{{class ErrorLocalElement

function fn

input Integer i;
output Integer o;

algorithm

o := match i

local

type t = Integer;
T t;

case t then t;

end match;

end fn;

constant Integer i = fn(1);

end ErrorLocalElement;}}}

There is similar code in the compiler that needs to be fixed (the compiler introduces new types that are subtypeof Any).

Fixed in r6924 with testcase meta/ErrorLocalElement.mo
