  -----------
  [OpenMP][libomp] Parameterize affinity functions

This patch parameterizes the affinity initialization code to allow multiple
affinity settings. Almost all global affinity settings are consolidated
and put into a structure kmp_affinity_t. This is in anticipation of the
addition of hidden helper affinity which will have the same syntax and
semantics as KMP_AFFINITY only for the hidden helper team.

  -----------
  [OpenMP][libomp] Add hidden helper affinity

Add new hidden helper affinity via the environment variable,
KMP_HIDDEN_HELPER_AFFINITY, which allows users to assign thread
affinity to hidden helper threads using the same syntax as
KMP_AFFINITY. OMP_PLACES/OMP_PROC_BIND have no interaction with
KMP_HIDDEN_HELPER_AFFINITY.
