6b3f3922bf [mips] Implement jr.hb and jalr.hb (Jump Register and Jump and Link Register with Hazard Barrier). 
Summary: These instructions are available in ISAs >= mips32/mips64. For mips32r6/mips64r6, jr.hb has a new encoding format.

a3953a30b6 [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

ebf9f0c6cb [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.
