Stop checking dtype for better optimization chance in BitOpTree (#2909)
* Tests: Add more case that does not match native C++ width (8, 16, 32 or 64).

* Use AstVarRef::same() instead of AstNode::sameGateTree() because the latter checks dtype in addition to scope.

AstVarRef may have different minWidth in some cases,
but the difference should be ignored in the context of bitOpTree optimization.
