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

[1] Special copy constructor used for initializing base and synthetic multifields
jatin-bhateja@0fe3153
[2] Fix ciField population for multifields
jatin-bhateja@4a26aff
[3] Multifield handling during type domain buildup

[4] prevent store forwarding across CPU memory barrier
jatin-bhateja@cfc71ac
[5] Fix to accommodate additional padding during offset computation of multifields
