[PATCH] D35253: [mips][mt][6/7] Add support for mftr, mttr instructions.

[Simon Dardis via Phabricator via llvm-commits]

Unlike many other instructions, these instructions have aliases which
take coprocessor registers, gpr register, accumulator (and dsp accumulator)
registers, floating point registers, floating point control registers and 
coprocessor 2 data and control operands.c

For the moment, these aliases are treated as pseudo instructions which are 
expanded into the underlying instruction. As a result, disassembling these
instructions shows the underlying instruction and not the alias.
