Properly handle DMD-internal "reference variables".

Browse Source 
Previously, we just had a hack to make ref foreach statements work.
This commit enables them to work in other cases as well, like the
implicit __result variable for functions with out-contracts (which
is such a magic ref variable for ref-returning functions).

Fixes DMD testcase 'testcontracts'.
