I have a patch that introduces indexMask to fix no suitable species for
indexMap vectorization of Gather/Scatter VectorAPI in Long/DoubleMaxVector.
Please see JBS for details.

Besides indexMask, I also changed Long/DoubleMaxVector's gather/scatter test codes 
to avoid failure caused by IndexOutOfBoundsException for unset mask lanes [1].

This patch has been verified by testing.
