Add LLVM support for remaining integer divide and permute instructions from ISA 2.06

Browse Source 
This is the patch corresponding to review:
http://reviews.llvm.org/D8406

It adds some missing instructions from ISA 2.06 to the PPC back end.

//===-------------------------------------------------------------------------===
Naming convention for instruction formats is very haphazard.
We have agreed on a naming scheme as follows:
<INST_form>{_<OP_type><OP_len>}+
Where:
INST_form is the instruction format (X-form, etc.)
OP_type is the operand type - one of OPC (opcode), RD (register destination),
RS (register source),
RDp (destination register pair),
RSp (source register pair), IM (immediate),
XO (extended opcode)
OP_len is the length of the operand in bits
VSX register operands would be of length 6 (split across two fields),
condition register fields of length 3.
We would not need denote reserved fields in names of instruction formats.
//===----------------------------------------------------------------------===//
Instruction fusion was introduced in ISA 2.06 and more opportunities added in
