Some of the instructions in the Mips instruction set are revision
delimited. llvm-mc -disassemble access these through the -mattr
option.
llvm-objdump -disassemble had no such way to set the attribute so
some instructions were just not recognized for disassembly.
This patch accepts llvm-mc mechanism for specifying the attributes.
