Microbenchmarks: disable Wasm baseline compiler

vouillon · hhugo · commit 86beb38cd075 · 2025-06-11T14:45:17.000+02:00
We are interested in the performance of optimized code. But V8 is
currently not able to switch to optimized code while executing a loop in
Wasm. So, we can get stuck running unoptimized code.
