Add support to llvm-readobj to decode the actual opcodes. The ARM EHABI opcodes are a variable length instruction set that describe the operations required for properly unwinding stack frames. The primary motivation for this change is to ease the creation of tests for the ARM EHABI object emission as well as the unwinding directive handling in the ARM IAS. Thanks to Logan Chien for an extra test case! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199708 91177308-0d34-0410-b5e6-96231b3b80d8
