16:#define STATE_COUNT 6432
17:#define LARGE_STATE_COUNT 1254

The case statement count in ts_lex reduced from 4040 to 3290, while the total state count doesn't change much.
Time to verify the statement that wasm compilation time is mainly determined by ts_lex case count.

Sadly, tree-sitter build -w keeps pulling the docker image of wrong arch on my arm64 machine.
Have to rely on your test number, @fdncred.

One more failing case compared to previous ver:

echo e>foo
echo err>>foo

But I checked nu_scripts, seems nobody actually writes crazy stuff like that

Thanks. I'll post timing in the tracking issue.
