Bug report

Bug description:

When Tools/scripts/summarize_stats.py is used to compare two stats .json files, it compares opcode counts by the opcode number, not the opcode name. This is a problem when comparing between two commits where the opcode numbers have changed (due to adding or removing opcodes).

If stats instead:

1. Emitted the opcode name rather than the number
2. summarize_stats.py used names rather than numbers

we should have something much more robust.
