Summary

This patch enables context sensitive PGO (CSPGO) for LTO on AIX. Two parts are involved:

  1. Frontend logic is added so libLTO can understand the CSPGO related options.
  2. Two options are added to the backend so that the LTOCodeGenerator can understand the CSPGO related options and make use of them.
