Subject: Implement i8x16.popcnt (#3286)

As proposed in https://github.com/WebAssembly/simd/pull/379. Since this
instruction is still being evaluated for inclusion in the SIMD proposal, this PR
does not add support for it to the C/JS APIs or to the fuzzer. This PR also
performs a drive-by fix for unrelated instructions in c-api-kitchen-sink.c
