tools: add support for decoding ARM attributes
Browse files Browse the repository at this point in the history 
Enhance the ARM specific parsing support in llvm-readobj to support attributes.
This allows for simpler tests to validate encoding of the build attributes as
specified in the ARM ELF specification.
