Mark Adler's original CRC32C implementation that is embedded in librdkafka as src/crc32c.c contains a hardware implementation using SSE4.2 that is compatible with gcc/clang inline assembler, but not with MSVC assembler.

It would be great if someone familar with MSVC assembler would port it (using #ifdef _MSC_VER guards).
