[PATCH MIPS][LS3A] Add Loongson3A specific instructions

[Mingjie Xing <mingjie dot xing at gmail dot com>]

Hello,

I prepared a patch to add Loongson3A specific instructions.  Tested on
the cross compilation platform.

I'm not sure if the test cases are good enough.  Suggestions are welcome.

Thanks,
Mingjie
