[StackMaps] Add location size to llvm-readobj -stackmap output
The size field of a location can be different for each entry, so it is useful to have this displayed in the output of llvm-readobj -stackmap. Below is an example of how the output would look: Record ID: 2882400000, instruction offset: 16 3 locations: #1: Constant 1, size: 8 #2: Constant 2, size: 8 #3: Constant 3, size: 8 0 live-outs: [ ] Patch By: jacob.hughes@kcl.ac.uk (with heavy modification by me) Differential Revision: https://reviews.llvm.org/D59169 llvm-svn: 358324
