IRGen: Disregard uncurry level of property accessors when mangling.

We mangle the type of the property, not the type of the accessor, so the uncurry level of the accessor is irrelevant to the mangler and causes the mangler to mangle properties of function type incorrectly--'var x : () -> ()', for instance, gets mangled to '_T6module1xfT_T_g' (with a lowercase uncurried 'f') instead of the proper '_T6module1xFT_T_g'. This broke the ListMaker test because SILGen and IRGen were coming up with inconsistent manglings for the 'handler' property of UndoManager in NSUndoManagerExts. Fixes <rdar://problem/13926113>.
