semantics of ISD::BSWAP
The custom node PPCISD::XXREVERSE has completely the same semantics of generic node ISD::BSWAP.
We need to clean up it as we have the combine rules for bswap in the base class, while nothing for xxreverse.

As part of the unification of the debug format and the MIR format, print
MBB references as '%bb.5'.
The MIR printer prints the IR name of a MBB only for block definitions.

Power9 has instructions that will reverse the bytes within an element for all
sizes (half-word, word, double-word and quad-word). These can be used for the
vec_revb builtins in altivec.h. However, we implement these to match vector
shuffle nodes as that will cover both the builtins and vector shuffles that
occur in the SDAG through other means.
