This is to prevent unnecessary script contexts to be created for
native scripts, which could end up with a script context table
containing twenty script contexts for a newly created native context.

Add Object::StrictEquals to unify the implementation of strict equality
comparison in the runtime and the api (the api was already missing a
case for SIMD).  Now we (almost) have a single bottleneck for strict
equality, we just need to reduce the amount of unnecessary complexity
for the code stub.

Second item in section 13.7.5.1 states that the error should be a
SyntaxError, when previously CheckAndRewriteReferenceExpression

Previously, all extras were "experimental" and left out of the snapshot. This
patch moves them to the snapshot, so now all extras are non-experimental. A
future patch will re-introduce experimental extras as part of the linked bug.

Restricts linux perf-event code range reporting to functions only (i.e. on

- Make the API look like v8::V8::InitializeICU.
  (That is: A static method call, not an object to be created on the stack.)
- Fix path separator on Windows, by calling base::OS::isPathSeparator.
- Move into API, so that it can be called by hello-world & friends.
- Actually call it from hello-world and friends.

This CL is a pure refactoring that makes an empty compilation unit
including just "foo.h" but not "foo-inl.h" compile without warnings or
errors. This is needed to further reduce the header dependency tangle.

This realizes above state for "spaces.h" and "mark-compact.h".

This tries to remove includes of "-inl.h" headers from normal ".h"
headers, thereby reducing the chance of any cyclic dependencies and
decreasing the average size of our compilation units.

Note that this change still leaves 5 violations of that rule in the
code. It only tackles "node.h" including "types-inl.h".

This test enumerates properties on all the builtins and makes sure that
they never change. In practice, this just generates busywork when trying
to add new language features; I've never seen it catch an
accidentally-exposed bit of API.

Modifies the BytecodeArrayBuilder to create register operands which are
negative. This reduces the number of instructions to access registers
by the interpreter and allows us to use positive register operands to
access parameter values.

Adds a Register class to keep register usage typesafe and simplify the
convertion to bytecode operand values.
