* passes.def (pass_all_early_optimizations): Add early phi-opt
after dce.
* tree-ssa-phiopt.c (value_replacement): Ignore NOPs and predicts in
addition to debug stmts.
(tree_ssa_phiopt_worker): Add early_p argument, do only min/max
and abs replacement early.
* tree-cfg.c (gimple_empty_block_p): Likewise.
* g++.dg/tree-ssa/phiopt-1.C: New testcase.
g++.dg/vect/slp-pr87105.cc: Likewise.
* g++.dg/tree-ssa/pr21463.C: Scan phiopt2 because this testcase
relies on phiprop run before.
* g++.dg/tree-ssa/pr30738.C: Likewise.
* g++.dg/tree-ssa/pr57380.C: Likewise.
* gcc.dg/tree-ssa/pr84859.c: Likewise.
* gcc.dg/tree-ssa/pr45397.c: Scan phiopt2 because phiopt1 is
confused by copies in the IL left by EVRP.
* gcc.dg/tree-ssa/phi-opt-5.c: Likewise, this time confused
by predictors.
* gcc.dg/tree-ssa/phi-opt-12.c: Scan phiopt2.
* gcc.dg/pr24574.c: Likewise.
* g++.dg/tree-ssa/pr86544.C: Scan phiopt4.
