Hi,

This patch adds support for emulation of CRC32 instructions for
the Mips target in QEMU, and enables CRC for mips64r6.

The CRC32 instructions are available in MD00087 Revision 6.06.
Since the disassembly for crc32 is hidden in commit 99029be1c28, the new
version of the patch is basically identical to the version 1, except
tests being added.

Kind regards,
Aleksandar Rakic
