target/mips: Allow executing MSA instructions on Loongson-3A4000
The Loongson-3A4000 is a GS464V-based processor with MIPS MSA ASE:
https://www.mail-archive.com/qemu-devel@nongnu.org/msg763059.html
Commit af868995e1b correctly set the 'MSA present' bit of Config3
register, but forgot to allow the MSA instructions decoding in
insn_flags, so executing them triggers a 'Reserved Instruction'.
Fix by adding the ASE_MSA mask to insn_flags.
Fixes: af868995e1b ("target/mips: Add Loongson-3 CPU definition")
