[llvm-objdump] Support detection of feature bits from the object and implement this for Mips. Summary: The Mips implementation only covers the feature bits described by the ELF e_flags so far. Mips stores additional feature bits such as MSA in the .MIPS.abiflags section. Also fixed a small bug this revealed where microMIPS wouldn't add the EF_MIPS_MICROMIPS flag when using -filetype=obj.

RUN: llvm-objdump -disassemble %p/../Inputs/dext-test.elf-mips64r2 | FileCheck %s
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. llvm-svn: 162781
