:wave: Hey,

In #4498 it was proposed that we should only accept i32 indices to br_table. The rationale for this is that larger types lead the users to a false sense of flexibility (since we don't support jump tables larger than u32's), and narrower types are not well tested paths that would be safer if we removed them.

Fixes #4498

I believe ireduce can directly go from i128 to i32.
