[PATCH] D34887: [mips] Implement the 'dext' aliases and it's disassembly alias.

[Simon Dardis via Phabricator via llvm-commits]

The other members of the dext family of instructions (dextm, dextu) are
traditionally handled by the assembler selecting the right variant of
'dext' depending on the values of the position and size operands.

When these instructions are disassembled, rather than reporting the
actual instruction, an equivalent aliased form of 'dext' is generated
and is reported. This is to mimic the behaviour of binutils.
