RFR: CODETOOLS-7902947: jcstress: Skip affinity initialization when non-local affinity mode is requested [v2]

[Aleksey Shipilev]

> Currently, we eagerly initialize affinity support in ForkedMain, even when local affinity mode is not enabled. This eats precious time that we spend on doing unnecessary work.

Aleksey Shipilev has updated the pull request incrementally with one additional commit since the last revision:

  Avoid dumping local affinity map when local affinity is disabled
