[PULL 07/14] linux-user: Add support for MIPS Loongson 2F/3A |

From: Philippe Mathieu-Daudé <f4bug@amsat.org>
Userland ELF binaries using Loongson SIMD instructions have the
HWCAP_LOONGSON_MMI bit set [1].
Binaries compiled for Loongson 3A [2] have the HWCAP_LOONGSON_EXT
bit set for the LQ / SQ instructions.
[1] commit 8e2d5831e4b ("target/mips: Legalize Loongson insn flags")
[2] commit af868995e1b ("target/mips: Add Loongson-3 CPU definition")
