Philip Reames 689c7c0532 [StackMaps] Update llvm-readobj to parse V3 Stackmaps ...

This updates the StackMap parser in the llvm-readobj tool to parse version 3 StackMaps, which were bumped in https://reviews.llvm.org/D32629.

Version 3 StackMaps differ in that they have a uint16 sized "location size" field which was added to the Location block in a StackMap record. The record has additional padding for alignment. This was a backwards incompatible change resulting in a StackMap version bump.

Patch By: jacob.hughes@kcl.ac.uk (with a rewrite of tests by me)
