A few more MIPS fixes. Emulator boots up with black screen.
The emulator no longer reboots on startup, though the screen remains
black. In this change:
- Fixed compilation of kMipsDelta.
- Fixed resolution trampoline to call with reg T9 so GP can be
calculated properly.
- Supress DescribeLocks on proxy methods to allow stack dumping (not
MIPS specific).
