Zvi Rackover a941bfb850 InstSimplify: Add a hook for shufflevector

Summary:
Add a hook for simplification of shufflevector's with the following rules:
- Constant folding - NFC, as it was already being done by the default handler.
-  If only one of the operands is constant, constant fold the shuffle if the
    mask does not select elements from the variable operand -  to show the hook is firing and affecting the test-cases.
