Hi,

This patch series adds support for emulation of CRC32 instructions for
the Mips target in QEMU, enables CRC for mips64r6, skips NaN mode check
for soft-float, and adds a CLI flag for enabling an MSA feature.

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 1/3 is basically identical to v1, except tests
being added.

Most of the following patches are cherry-picked from the branch
mips_rel/4_1_0/master on the MIPS' repository:
https://github.com/MIPS/gnutools-qemu/
Further details on individual changes are included in the respective
patches.

Kind regards,
Aleksandar Rakic
