[corona10]

• Issue: dead store elimination in the compiler #104635

Benchmarks

import pyperf

runner = pyperf.Runner()
runner.timeit(name="bench dead_store",
              stmt="""
_, _, _, a = 1, 2, 3, 4

Mean +- std dev: [base] 11.7 ns +- 0.2 ns -> [opt] 11.1 ns +- 0.1 ns: 1.05x faster

    return a

Mean +- std dev: [static_base] 27.1 ns +- 0.3 ns -> [static_opt] 26.0 ns +- 0.2 ns: 1.04x faster

Mark's change + dead_store elimination + apply_static_swaps makes 3-5% faster without adding super instruction.

8 instructions -> 5 instructions

7 instructions -> 5 instructions

@carljm Can you please take a look at?

LGTM!
