Qiongsi Wu 3faab85c12 [AIX][LTO] Enabling Context Sensitive PGO Options
This patch enables context sensitive PGO (CSPGO) for LTO on AIX. Two parts are involved:

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