PTAL. In addition to this, there are two more OSR errors on mips64 to be tracked
down, and fixed in separate CL.

Probably due to some frame layout details or some preserved register that I
overlooked. Are the frames on MIPS64 laid out significantly differently than on
MIPS?

I mistakenly attributed 2 TF test fails here. They surfaced after
https://codereview.chromium.org/1018853003, and Dusan just fixed the problem in
https://codereview.chromium.org/1038173003. Nothing to do with frame layout or
any of your changes. FYI, JS frames are laid out the same on both MIPS & MIPS64.
C frames are a bit different due to ABI.
