[Beignet] [PATCH v2 0/8] phi out-of-SSA optimization patchset.

[Zhigang Gong]

This is new version with fixes to address comments.
Only the 7th one 
" GBE: Fix one DAG analysis issue and enable multiple round phi copy
    elimOAination."
is not reviewed yet. But it is required for this patchset, and I also made
some change in it, so I sent it out together with other reviewed/modified
patches.

Zhigang Gong (8):
  GBE: refine Phi copy interfering check.
  GBE: refine liveness analysis.
  GBE: add two helper routines for liveness partially update.
  GBE: add some dag helper routines to check registers' interfering.
  GBE: implement further phi mov optimization based on intra-BB
    interefering analysis.
  GBE: continue to refine interfering check.
  GBE: Fix one DAG analysis issue and enable multiple round phi copy
    elimination.
  GBE: avoid vector registers when there is high register pressure.
