This updates the StackMap parser in the llvm-readobj tool to parse version 3 StackMaps, which were bumped in this revision[1].

Version 3 StackMaps differ in that they have a uint16 sized "location size" field 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.

This change also includes the size of each location in the printed output.
