Subject: [dataflow][PATCH] Regression fixes for SPARC

Hi,

The attached patch fixes all extra regressions of dataflow branch on SPARC.
Bootstrapped and reg-tested on SPARC.

OK?

PS. Thanks to Steven Bosscher for pointing me in the right direction
for gcse.c fix.

       * df-scan.c (df_get_exit-block_use_set): Always add the stack pointer
       to the exit block use set.
       * gcse.c (cpro_jump): Don't emit barrier in cfglayout mode.
       * config/sparc/sparc.c (sparc_check_64): Check df != NULL.
