[PATCH] Optimize scattered vector insert/extract pattern

[Lawrence Hu]

Hi, Nadav:

Thanks for your comments.

This is a joint patch between I and Ana, Yes I noticed there are some codes for insertElement, however since it doesn't catch our case, I didn't check if it could be expanded.

Sorry for the late reply, I was asked to focus on a release feature,  I will go to it and take a detailed look after this feature is done, hopefully this week or next week.

Thanks

Lawrence Hu
