For details, see: https://github.com/tinygo-org/tinygo/pull/3927 I ran the smoke tests and the binaries are exactly identical to what they were before, so this change cannot have had an effect on these smoke tests (which is expected, as this is mostly just changing some types without changing the machine data type).
