Add UOp Pair counts to pystats #115178
Description
Feature or enhancement
Proposal:
Add a new section to the stats produced by --enable-pystats, which keeps track of the pairs, triples, and longer sequences in which UOps appear. This will be useful for analyzing candidate pairs for condensing into a single superinstruction, as well as other kinds of optimization.
Has this already been discussed elsewhere?
No response given

This came up in the context of exploring superinstructions for the Copy and Patch JIT at faster-cpython/ideas#647.
