Inline relevant bits from Map::FindUpdatedMap() and Map::IsMoreGeneralThan()
into Map::CurrentMapForDeprecatedInternal() to fix issues introduced
with field type tracking, avoid the useless second pass over the transition
tree, and finally make it easier to understand what this method actually
does.

Also fix TryMigrateInstance() to return bool instead of the parameter or
a null handle.

Port r20974 (5de4367)

Original commit message:
- Don't bake in length/capacity into full codegen calls of stubs,
allowing boilerplates to increase their capacity without regenerating
code.
- Unify all variants of the clone stub into a single,
length-independent version.
- Various tweaks to make sure that the clone stub doesn't spill and
therefore need an eager stack frame.
- Handle all lengths of array literals in the fast case.

This fixes the following generated code sequence:
  movn w1, #0     // Synthesize -1.
  cmp w0, w1

With a properly-constructed Operand, the MacroAssembler can optimize it
as follows:
  cmn w0, #1

Don't use OS::MemCopy in BitCast. It's crucial that the compiler can

I have fixed skipping of the receiver object to materialize captured
objects. This is done with a new DoTranslateSkip method.

We should consider unifying DoTranslateSkip, DoTranslateObject and
DoTranslateCommand as they do the almost the same thing - they only
differ in where they store the result.

The change also turns bunch of ASSERTs into CHECKs.

Don't adopt the AST id from previous if id is none, since previous may have mismatching expected stack height.
Additionally, harden merging of simulates after instructions with side effects and ensure there's a simulate before HEnterInlined.

Adds new Traits::Type::StatementList definitions both for Parser and
PreParser, and the corresponding NewStatementList() factory function.
This is needed to be able to define in ParserBase parsing functions
that return and manipulate lists of statements.

Moving and renaming PreParser::Statement to PreParserStatement is also
needed so its definition is available earlier for PreParserStatementList
to use it.

Added an Isolate* field to NoTrackDoubleFieldsForSerializerScope, PlatformFeatureScope and BinaryOpIC::State.

The serializer state and even the CPU features will be per-Isolate
later. Currently we get away with global state, because mksnapshot
runs single-threaded and has only 1 Isolate, but this will change.
Furthermore, these changes are yet another prerequisite for removing a
catch-22 at initialization time when we try to enable serialization.

This CL is similar in spirit to r20919, BTW.
