Description

MySQL 5.6 introduced innodb_checksum_algorithm=crc32 and implemented it for AMD64 using the SSE 4.2 instructions (incorrectly advertised as "SSE2" in a startup message). It was not implemented on IA-32 or on Windows.

Since MariaDB 10.2.11, MariaDB makes use of the SSE4.2 CRC-32C instructions on Windows on both IA-32 and AMD64.

Let us be consistent and implement CRC-32C for IA-32 on all available platforms.
