Add replication to LOAD_FAST_BORROW to speed up the JIT #134140
Description
Feature or enhancement
Proposal:
This is relatively straightforward, but requires a lot of googling issue/PR searching before understanding what's happening. Please don't take this issue unless you're a sprinter at PyCon US, and if you want to take it there, ask @brandtbucher.
Basically, LOAD_FAST has replicate(x) in bytecodes.c, but not LOAD_FAST_BORROW. Considering LOAD_FAST_BORROW is now more common than LOAD_FAST, we should replicate it.
Reserving this issue for someone sprinting at PyCon US, to welcome them to the community with a fairly small-scale, but likely to improve performance issue.
