Toma Tabacu 3d5ce49ce5 [TableGen] Prevent invalid code generation when emitting AssemblerPredicate conditions. ...

Summary:
The loop which emits AssemblerPredicate conditions also links them together by emitting a '&&'.
If the 1st predicate is not an AssemblerPredicate, while the 2nd one is, nothing gets emitted for the 1st one, but we still emit the '&&' because of the 2nd predicate.
This generated code looks like "( && Cond2)" and is invalid.
