PowerPC64 extended instructions in powerpc_macros
The extended instructions implemented in powerpc_macros aren't used by
the disassembler. That means instructions like "sldi r3,r3,2" appear
in disassembly as "rldicr r3,r3,2,61", which is annoying since many
other extended instructions are shown.
Note that some of the instructions moved out of the macro table to the
opcode table won't appear in disassembly, because they are aliases
rather than a subset of the underlying raw instruction. If enabled,
rotrdi, extrdi, extldi, clrlsldi, and insrdi would replace all
occurrences of rotldi, rldicl, rldicr, rldic and rldimi. (Or many
occurrences in the case of clrlsldi if n <= b was added to the extract
functions.)
The patch also fixes a small bug in opcode sanity checking.
