PTAL.

Nice change! LGTM. However, I did not get a chance to run tests on this. If you
have, please go ahead and land it.

File src/mips/constants-mips.h (right):

src/mips/constants-mips.h:782: mode_round = RN,
nit: suggest kMode_round, etc. A little closer to naming convention, but still
lets you stringify the opcode.
