Add flag to capture missing intrinsics when running application

The flag -XX:+DebugVectorApiMissingIntrinsics is useful to find
what Vector API methods are not intrinsified. This tends to print
more than necessary including lambda methods which are called due
to higher level API functionality being called, but it is a good
guide to help detect what is missing.
