Merge lworld

[jatin-bhateja]

Merge from lworld in lworld+vector branch.

Apart from the usual merge conflict resolution, the patch also contains bug fixes for some special handling around multifields. To segregate the code changes and maintain the history[1][2][3][4][5], these bug fixes were initially checked into a temporary private merge branch and are now part of the merge.

Validation: Status

• Vector API JTREG tests
  • Default options:
  • With -XX:+DeoptimizeALot
  • With -XX:-UseNonAtomicValueFlattening
• Valhalla JTREG tests
