3a91adaec8 Classes: Add support for arguments in default constructor 
This is currently done by generating a default constructor that looks
like this:

  constructor() {
    %DefaultConstructorSuperCall();
  }

The a runtime function implements the logic which is pretty similar to
Runtime_Apply except that it uses the [[Prototype]] of the current
function.

5044c510cb Don't print inlined function ID in --trace-hydrogen 
FunctionLiteral has two purposes: it is a unit of compilation, and it is
also an expression.  Its id() is only for the latter purpose, used by
the continuation of the closure, not by the closure itself.

When we inline, we treat the FunctionLiteral as a unit of compilation,
not as an expression, and as such the FunctionLiteral doesn't have any
meaningful ID.  The right thing to do is not to access the ID when
printing the hydrogen expression.

3b3929fdc7 Reland "Avoid some unnecessary fast-properties map creations." 
This relands commit ea74f0f85a.

The revert was due to failures in cctest/test-heap/ReleaseOverReservedPages,
caused by apparent changes to memory layout and fragmentation of the
first page. Eliminating a situation in messages.js where this CL has had
an effect on map transitions seems to solve the issue.

e13996e96d Remove V8.ZoneSegmentBytes. 
1) It's unused. 2) Since Zones can be used on a background thread, the Zone
cannot just access this counter from the Isolate, so keeping this counter up to
date would require extra work. Better to just remove it.

b9886ae9ff Fix bugs in simplified lowering relating to int32/uint32 signs. 
Lowering of NumberToUint32 and NumberToInt32 was not correctly accounting for the sign of the input and the sign of the output, emitting the wrong representation changes.

Along the way, I've found cases where MachineOperatorBuilder would break if fed a machine type for loads or stores that was not cached, requiring MachineOperatorBuilder to take zone to allocate operators for these cases.

406fa443e7 X87: Turn ToNumberStub into a PlatformCodeStub again. 
port b6737c56eaf51d63ab83b6529f657c15f834623c (r25187)

original commit message:

  Turn ToNumberStub into a PlatformCodeStub again.

  The HydrogenCodeStub is too expensive and there's no easy way to reduce
  this cost, so turning it into a PlatformCodeStub solves that problem until
  we can use TurboFan for code stubs.

Add MemoryOperandMatcher that recognizes node clusters in the form
[%r1 + %r2*SCALE + OFFSET] and explicit support in the x64 Int32Add

ea74f0f85a Avoid some unnecessary fast-properties map creations. 
(1) When we have just normalized and re-fastified a map, we don't need to copy it again to set the is_prototype bit.
(2) When defining accessors causes a non-prototype object to go slow, don't force re-fastification.

1a64b02dcf harmony_scoping: Implement lexical bindings at top level 
This implements correct semantics for "extensible" top level lexical scope.
The entire lexical scope is represented at runtime by GlobalContextTable, reachable from native context and accumulating global contexts from every script loaded into the context.

When the new script starts executing, it does the following validation:
- checks the GlobalContextTable and global object (non-configurable own) properties against the set of declarations it introduces and reports potential conflicts.
- invalidates the conflicting PropertyCells on global object, so that any code depending on them will miss/deopt causing any contextual lookups to be reexecuted under the new bindings
- adds the lexical bindings it introduces to the GlobalContextTable

Loads and stores for contextual lookups are modified so that they check the GlobalContextTable before looking up properties on global object, thus implementing the shadowing of global object properties by lexical declarations.

2b026851ac Scanner: disallow unicode escapes in regexp flags. 
The spec explicitly forbids them. V8 never handled them properly either, just
the Scanner accepted them (it had code to add them literally to the
LiteralBuffer) and later on, Regexp constructor disallowed them.

According to the spec, unicode escapes in regexp flags should be an early error
("It is a Syntax Error if IdentifierPart contains a Unicode escape sequence.").

Note that Scanner is still more relaxed about regexp flags than the
spec. Especially, it accepts any identifier parts (not just a small set of
letters) and doesn't check for duplicates.
