RFR: 8321648: Integral gather optimized mask computation.

Mon Dec 11 07:36:30 UTC 2023

Hi,

This bug fix patch optimizes integral gather mask computation using cheaper instruction and fixes incorrect instruction attributes in legacy integral gather instructions.

All Vector API JTREG tests are passing with this at various AVX levels.

Kindly review and share feedback.

Best Regards,
Jatin
