Our test infrastructure ignores missing tests which are listed in
status files. Sometimes, tests are removed and status file lines
are not updated. This patch adds a presubmit check for status
files addressing JavaScript tests to not reference missing tests.
It also cleans up existing violations.

This patch adds parsing of spread object property.

-- Changes ParsePropertyName to parse Token::ELLIPSIS.
-- Throws if rest is encountered by setting a pattern error.
-- Adds a new PropertyKind enum (SPREAD)
-- Adds a new ObjectLiteralProperty::kind (SPREAD)
-- Adds a new harmony-object-spread flag and protects the parser code
with it.
-- Adds a new runtime function called CopyDataProperties
-- Does not add any support for this feature in fullcodegen.
-- Ignition calls out to a runtime function CopyDataProperties to
perform spread operation.
-- Move FastAssign from builtins-objects.cc to objects.cc
-- Refactor Builtin_ObjectAssign to use SetOrCopyDataProperties

Object rest will be implemented in a follow on patch.

Add a feedback vector slot for computed property names in object
and class literals. Introduce new slot kind for storing
computed property names.

Change StaDataPropertyInLiteral to use the accumulator (again), so
we don't exceed Bytecodes::kMaxOperands.

We assume that most computed property names are
symbols. Therefore we should see performance
improvements, even if we deal with monomorphic ICs only.

This CL only collects feedback but does not use
it in Reduce() yet.

  port 72c37076(r42034)

  original commit message:
  Currently the CompileLazy builtin checks the SFI expliciltly for FCG code. This means
  if the SFI has bytecode we have to go through to the runtime to install the
  interpreter entry trampoline into the JSFunction object.

  Modify the builtin to always put the SFI code object into the JSFunction unless it's
  the lazy compile stub on the SFI as well.

For benchmarks with multiple measurements (e.g. runtime, compile
time, generated code size), in case of error, we'd get only the
last portion of the name ("Compile"), which is ambiguous and makes
debugging dificult. This change includes the full name, e.g.
"Unity/Physics/Compile".

This moves the initialization of [[HomeObject]] for constructors from
the %DefineClass runtime function into the bytecode generator, and
makes it conditional (resolving an old TODO). As part of this refactor,
avoid a load of "prototype" by returning the class prototype from
%DefineClass.

This is one of many steps in moving more of class definition into
bytecode.
