Hi Folks,
Some support was added to enable a pass state of all validation tests for KNL for JDK9.  This support enables upper bank register usage for auto code generation for a small number of instructions (3) which needed some additional coverage under cases where servers do not enable vector length but have EVEX support.

This code was tested as follows: All internal validation tests at both Intel and Oracle.  This change needs approval for JDK9 addition.
