This makes the logic in the Hydrogen->Lithium translation much clearer, avoids a
hand-written dispatch and even opened up opportunities for simpler register
constraints for some operations/platforms.

Doing the same for the Hydrogen level might be done in a follow-up CL.

The right moment for fixing style errors is when working on the CL, not when
committing it. And this makes non-committers bump into this check too when
uploading changes.

Native method invocation from the arm/simulator-arm.cc previously made
non-portable assumptions about calling conventions. This was okay for 32-bit
stack-based machines, where by-value structs are automatically materialized
on the stack, and where both int and double parameters could be passed on the
stack. However they are not okay for x86-64, which has an elaborate scheme
for passing parameters in registers.

This CL replaces the previous non-portable code paths with portable code,
using call-sites that accurately match the prototype of the callee.

Specifically:
- Introduce Symbol and SymbolObject classes.
- Generalise Object::Has and Object::Delete to arbitrary Value-typed keys.
- Generalise some places in the API implementation from String to Name.

It is not possible to intercept symbol-named properties. That is consistent with the idea that symbols are private and should not leak.

The new test checks full CPU profiling cycle: using public
V8 API it starts profiling, executes a script, stops profiling
and analyzes collected profile to check that its top-down
tree has expected strutcture. The script that is being profiled
is guaranteed to run > 200ms to make sure enough samples
are collected.

To avoid possible flakiness due to non-deterministic time required
to start new thread on varios OSs when Sampler and ProfilerEventsProcessor
threads are being started the main thread is blocked until the threads
are running.

Also I removed the heuristic in profile-generator.cc where we try
to figure out if the value on top of the sampled stack is return address
of some frameless stub invocation. The code periodically gives false positive
with the new test ending up in an extra node in the collected cpu profile.
After discussion with jkummerow@ we concluded that the logic is too fragile
and that we can address frameless stub invocations in a more reliable way
later should they have a noticeable effect on cpu profiling.

This moves the responsibility of putting a new context into a persistent
handle to the embedder. Also it removes one API function where the copy
