From: Chinmay Rath <rathc@linux.ibm.com>

Moving the following instructions to decodetree specification:

	v{and, andc, nand, or, orc, nor, xor, eqv}	: VX-form

The changes were verified by validating that the tcp ops generated by those
instructions remain the same, which were captured with the '-d in_asm,op' flag.
