Currently, ELFObjectFile is used to build a SubtargetFeatures object for MIPS. I've moved the MIPS specific code into its own function and then also created an ARM specific function which builds the features from quering the build attributes. Together with https://reviews.llvm.org/D28281 it enables llvm-objdump to automatically create an accurate target.
