Tested on the vectorizer testcases
Bootstrapped and passed full testing on powerpc-linux together with the
other parts of this patch.

thanks,
dorit

ChangeLog:

      * tree-vect-analyze.c (process_use): New function.
      (vect_mark_stmts_to_be_vectorized): Factor out code to process_use.
      Check phis in all bbs.
      * tree-vectorizer.c (vect_is_simple_use): Remove redundant checks.
