rs6000.c (validate_condition_mode): New function.
* config/rs6000/rs6000.c (validate_condition_mode): New function.
(branch_comparison_operator): Call validate_condition_mode to
abort rather than returning 0.
(branch_positive_comparison_operator): New function.
(scc_comparison_operator): Call validate_condition_mode to abort
rather than returning 0.
(ccr_bit): Call validate_condition_mode. Update for
new branch scheme.
(print_operand): Delete %C modifier. Update %E case
to use EQ bit not SO bit.
(rs6000_reverse_condition): New function.

for cr_logical instructions. Change length of branch
instructions.
