Avoid data race when writing Shell::options.script_executed.
The race occurred when Workers were used. Since Workers call
Shell::ExecuteString from a different thread, TSAN (correctly) flags
this as a racy write. Solution would be to either synchronize the writes,
or to 'lift' the write higher up in the call stack and only write the flag
from the main thread. This implements this latter solution.
These methods call Shell::ExecuteString, but do *not* set script_executed:
- ExecuteInThread: Can only occur is JS has already been executed.
- Shell::Load: Callback for JS; so JS has already been executed when
we get there.
- Shell::RunShell: Interactive shell. We no longer need script_executed once
we're here.

Remove high promotion mode
High promotion mode limits new space size in the case where many objects (high
rate) are promoted. The result is frequent scavenger runs with low pause times. The
approach conflicts with pretenuring which requires a larger new space size to

Ultimately the goal is to have pretenuring catch allocation sites that have high
promotion rates.

[stubs] Unify (and optimize) implementation of ToObject.
This is the initial (big) step towards a more uniform implementation of
the ToObject abstract operation (ES6 7.1.13), where we have a fallback
implementation in JSReceiver::ToObject() and a fast (hydrogen) CodeStub
to deal with the fast case (we should be able to do more cleanup on this
in a followup CL). For natives we expose the abstract operation via a
%_ToObject intrinsic, also exposed via a macro TO_OBJECT, that unifies
the previous confusion with TO_OBJECT_INLINE, ToObject, TO_OBJECT,
$toObject and %$toObject. Now the whole implementation of the abstract
operation is context independent, meaning we don't need any magic in the
builtins object nor the native context.

Fix the failure when enabling v8 profiler or vtune profiler in chromium.
When enabling the v8 profiler (Using the following command parameters: --js-flags=--prof)
or vtune profiling in chromium. it will break. This failure is introduced by this CL:
https://codereview.chromium.org/
1218863002.
The reason is that V8 will enable the JITted code logging if --prof is set for V8. And under
this condition, the function Logger::LogCodeObjects() will be invoked and it will trigger a
mark-compact GC when deserializing the snapshot. This GC will use MemoryReducer to post a
delay task by invoking V8Platform::CallDelayedOnForegroundThread() function. But at this point
V8 isolation is still under initialization and the PerIsolationData of this isolation has not
been created. (isolation_holder.cc:39~40 line). This leads to V8Platform::CallDelayedOnForegroundThread()
failure because of segment fault.
According to my understanding, I proposed the following fix. If the heap deserialization has not
be completed, it does not post the delay task for next GC.

Optimize ToNumber and NonNumberToNumber.
Moves some uncommon type checking from ToNumber and
NonNumberToNumber into DefaultNumber. This should
speed up numeric operations especially as more "value types
are added.

PPC: [stubs] Don't pass name to Load/StoreGlobalViaContext stubs.
Port
5dff4bdff06c0463db1e876af7541af2b715392c
Original commit message:
No need to pass the name explicitly to the stubs; the runtime can
extract the name from the ScopeInfo (the extension of the
ScriptContext) on-demand easily without any performance impact.
