e44d3b7a87 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... ;-)

a2e996a5fa 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.

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.

ffcc4de0d3 MIPS: ES6 symbols: Allow symbols as property names 
Port r13811 (0e64f280)

Original commit message:
Since symbols and strings share a common representation, most of this change is about consistently replacing 'String' with 'Name' in all places where property names are expected. In particular, no new logic at all is necessary for maps, property dictionaries, or transitions. :) The only places where an actual case distinction is needed have to do with generated type checks, and with conversions of names to strings (especially in logger and profiler).

Left in some TODOs wrt to the API: interceptors and native getters don't accept symbols as property names yet, because that would require extending the external v8.h.

f4abb7afc6 MIPS: ES6 symbols: Implement Symbol intrinsic and basic functionality 
Port r13786 (b5e7a82a)

Original commit message:
- Add --harmony-symbols flag.
- Add Symbol constructor; allow symbols as (unreplaced) return value from constructors.
- Introduce %CreateSymbol and %_IsSymbol natives and respective instructions.
- Extend 'typeof' code generation to handle symbols.
- Extend CompareIC with a UNIQUE_NAMES state that (uniformly) handles internalized strings and symbols.
- Property lookup delegates to SymbolDelegate object for symbols, which only carries the toString method.
- Extend Object.prototype.toString to recognise symbols.

Per the current draft spec, symbols are actually pseudo objects that are frozen with a null prototype and only one property (toString). For simplicity, we do not treat them as proper objects for now, although typeof will return "object". Only property access works as if they were (frozen) objects (via the internal delegate object).
