Subject: [dataflow][PATCH] Compute dominance information in ce2 pass.

Hi,

The attached patch fixes the performance regression on SPEC CPU2000 wupwise.
The mainline computes the dominance information in all ifconvert passes
except ce1, but  df doesn't compute it at all.

Bootstrap and regtest are still running.

       * ifcvt.c (if_convert): New parameter RECOMPUTE_DOMINANCE.
       (rest_of_handle_if_conversion, rest_of_handle_if_after_combine,
       rest_of_handle_if_after_reload): New parameter to if_convert.
