[issue45367] Specialize BINARY_MULTIPLY

[Dennis Sweeney]

New submission from Dennis Sweeney <sweeney.dennis650 at gmail.com>:

I'm having trouble setting up a rigorous benchmark (Windows doesn't want to install greenlet for pyperformance), but just running a couple of individual files, I got this:

Mean +- std dev: [nbody_main] 208 ms +- 2 ms -> [nbody_specialized] 180 ms +- 2 ms: 1.16x faster
Benchmark hidden because not significant (1): pidigits
Mean +- std dev: [chaos_main] 127 ms +- 2 ms -> [chaos_specialized] 120 ms +- 1 ms: 1.06x faster
Mean +- std dev: [spectral_norm_main] 190 ms +- 10 ms -> [spectral_norm_specialized] 175 ms +- 1 ms: 1.09x faster
Mean +- std dev: [raytrace_main] 588 ms +- 48 ms -> [raytrace_specialized] 540 ms +- 4 ms: 1.09x faster

Hopefully those are accurate.
