Revert "Add .dir-locals.el."

After some discussions, this seems to be the wrong approach. We should probably
either link to the Google style guide and its related configuration files, or
even add a Makefile target for downloading it.

Furthermore, with this change Emacs keeps popping up an annoying confirmation
window for new files.

Fixed register allocation corner case.

The predicate CanBeSpilled had a bug, prohibiting the necessary spilling and
correct splitting of live ranges. Removed a redundant assertion immediately done
by the callee anyway.

Thanks to Slava for help with that issue and the entertaining historical
background of the whole story... ;-)

MIPS: Unify deoptimizer for stub failure trampoline frames.

Port r13887 (6d146270)

Original commit message:
This unifies the translation of a compiled stub frame to a stub failure
trampoline frame. Only the frame's register allocation is different on
each architecture and can be factored out.
