I have a 16-core 7950X and a 16-core M3 MBP. They both build the Firefox source code in roughly the same amount of time...or would, but for the `wasm2c` invocation takes about 1 minute on the former and over 3 minutes on the latter.

For further discussion see: https://bugzilla.mozilla.org/show_bug.cgi?id=1867594#c6

Are there known reasons for wasm2c taking multiple times as long on ARM, and is there any prospect of that improving?
wasm2c is multiple times slower on Apple ARM processors (M3) than x86-64
