Hi,

This patch adds support for emulation of CRC32 instructions for
the Mips target in QEMU, adds tests, and enables CRC for mips64r6.
The CRC32 instructions are available in MD00087 Revision 6.06.
The disassembly for crc32 is hidden in commit 99029be1c28.
New opcode is implemented in decodetree format as in v3.

Kind regards,
Aleksandar Rakic
