[PATCH] [mips] Add support for branch-likely pseudo-instructions

[Daniel Sanders]

LGTM with a couple nits and a revised commit message.

> This work is based on http://reviews.llvm.org/D8537


Nit: Please reference r239905 rather than http://reviews.llvm.org/D8537 when you commit.

There's rarely a need to reference the MIPS bugzilla here. http://llvm.org/PR22994 is the LLVM ticket for this.
