From: Chinmay Rath <rathc@linux.ibm.com>
Moving the below instructions to decodetree specification :
andi[s]., {ori, xori}[s] : D-form
{and, andc, nand, or, orc, nor, xor, eqv}[.],
exts{b, h, w}[.], cnt{l, t}z{w, d}[.],
popcnt{b, w, d}, prty{w, d}, cmp, bpermd : X-form
With this patch, all the fixed-point logical instructions have been
moved to decodetree.
The changes were verified by validating that the tcg ops generated by those
instructions remain the same, which were captured with the '-d in_asm,op' flag.
