Daniel Sanders 8dcb116a3e [mips] Implement tlbp, tlbr, tlbwi, and tlbwr

Daniel Sanders 3dc2c016a6 [mips] Split Instruction.Predicates into smaller lists and re-join them with !listconcat 
Summary:
The overall idea is to chop the Predicates list into subsets that are
usually overridden independently. This allows subclasses to partially
override the predicates of their superclasses without having to re-add all
the existing predicates.

This patch starts the process by moving HasStdEnc into a new
EncodingPredicates list and almost everything else into
AdditionalPredicates.

It has revealed a couple likely bugs where 'let Predicates' has removed
the HasStdEnc predicate.

No functional change (confirmed by diffing tablegen-erated files).

Depends on D3549, D3506

Kai Nacke 13673ac704 [mips] Add more Octeon cnMips instructions 
Adds the instructions ext/ext32/cins/cins32.
It also changes pop/dpop to accept the two operand version and
adds a simple pattern to generate baddu.
Tests for the two operand versions (including baddu/dmul/dpop/pop)
and the code generation pattern for baddu are included.

Kai Nacke 93fe5e810d [MIPS] Add cpu octeon and some instructions 
The Octeon cpu from Cavium Networks is mips64r2 based and has an extended
instruction set. In order to utilize this with LLVM, a new cpu feature "octeon"
and a subtarget feature "cnmips" is added. A small set of new instructions
(baddu, dmul, pop, dpop, seq, sne) is also added. LLVM generates dmul, pop and
dpop instructions with option -mcpu=octeon or -mattr=+cnmips.
