[AArch64] Fix the bit pattern order in the comments in auto-generated file 

The bit pattern comment in "aarch64_opcode_lookup_1" is reversed.

This patch fixed this.

opcode/
	* aarch64-gen.c (print_decision_tree_1): Reverse the index of PATTERN to
	correct the print.
	* aarch64-dis-2.c: Regenerated.
