[Beignet] [PATCH v3 0/9] phi out-of-SSA optimization patchset

[Zhigang Gong]

The major change in this version is in liveness helper routines and
add a new patch and remove the incorrect DAG fix bug.

  GBE: Don't try to remove instructions when liveness is in dynamic update phase.

Zhigang Gong (9):
  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: Don't try to remove instructions when liveness is in dynamic
    update phase.
  GBE: enable post phi copy optimization function.
  GBE: avoid vector registers when there is high register pressure.
