[CVP] Allow two transforms in one invocation

For a call site which had both constant deopt operands and nonnull arguments, we were missing the opportunity to recognize the later by bailing early.

This is somewhat of a speculative fix.  Months ago, I'd had a private report of performance and compile time regressions from the deopt operand folding.  I never received a test case.  However, the only possibility I see was that after that change CVP missed the nonnull fold, and we end up with a pass ordering/missed simplification issue.  So, since it's a real issue, fix it and hope.
