* tree-ssa-phiopt.c (tree_ssa_phiopt): Rewrite so we base the
bbs on the COND_EXPR instead of the PHI_NODEs.
(candidate_bb_for_phi_optimization): Remove.
(replace_phi_with_stmt): Rename to ...
(replace_phi_edge_with_variable): this and change so that we
replace the phi argument instead of removing the PHI.
(conditional_replacement): Change so we deal with PHI with more
than two arguments.
(value_replacement): Likewise.
(abs_replacement): Likewise.
