[Issue 6600] New: unrelated expression alters function name mangling

          Summary: unrelated expression alters function name mangling

void funOneArg()() {}
void func_pure_nothrow() pure nothrow {}

void foo()
{
   // commenting the next line in/out will change the mangling of *f2
   // enum f1 = &curry!funOneArg;
   enum f2 = &func_pure_nothrow;
   pragma(msg, typeof(*f2));
   pragma(msg, typeof(*f2).mangleof);
}

auto curry(alias fun, Args...)(Args args)
{
   return fun(args);
}

Roughly the issue is that the deco member for TypeFunction isn't updated
when purityLevel is deduced lazily.
In detail:
TypePointer for f1 and f2 are merged as their types are already equal when
evaluating the AddrExp.
Now both TypePointer alias the same TypeFunction but that was created from a
function without 'pure nothrow'. That's why the deco buffer does still contain
unattributed function.

There is also the side issue that f2's TypeFunction suddenly has an empty
tuple parameter.
