predicates.md (pcrel_address, [...]): Remove redundant conditionals. 

* config/m68k/predicates.md (pcrel_address, extend_operator,
	post_inc_operand, pre_dec_operand): Remove redundant
	conditionals.
	(const_uint32_operand, const_sint32_operand): Use gcc_assert
	instead of abort.
	(valid_dbcc_comparison_p): Rewrite in the lisp style.
