[PATCH, committed] PowerPC predicates.md

[David Edelsohn <dje at watson dot ibm dot com>]

	This patch fixes the bootstrap failure on libjava.
branch_comparison_operator was returning false because the mode did not
match.

David


	* config/rs6000/predicates.md (branch_comparison_operator): Change
	to define_special_predicate.
	(scc_comparison_operator): Same.
	(branch_positive_comparison_operator): Same.
