This CL changes GetHeapSpaceStatistics api to return SizeOfObjects()
instead of Size(). SizeOfObjects is the required field and is
consistent with GetHeapStatistics api.

...when handing out validity cells to handlers; because invalidating said cells is
the only time we'll need the user registrations.
Along the way, fix a corner case in WeakFixedArray, which can now be empty after
the recently introduced compaction support.

- instead of committing operands early to resolve hints, hold the hint register data on the UsePosition
- allow hints to be rolled back efficiently as needed by GreedyAllocator
- some small drive by fixes

This uses explicit operators instead of intrinsic runtime calls to
create literals froms boilerplates. It allows for easier access of
static parameters and syncs it with other allocating operators.

This introduces a JSCreateClosure operator which can be lowered by the
typed pipeline to the aforementioned stub. It also allows for further
optimizations of closure creation.

If the array's map is the initial FastHoley array map, and the array prototype
chain is undisturbed and empty of elements, then keyed loads can convert the
load of a hole to undefined.

This changes the unittests suite to be run in only the default variant,
because unit tests are (and should be) written to be independent from
global flags.

This reverts commit d5565c1f68.
Getter and setter function names in ES6 are defined as "get foo" and
"set foo".
This also moves the logic for handling symbols from runtime-function.cc
to v8natives.js.

Follow up for r28032.
We don't need to store the "corresponding outer scope class variables", it's
enough if we transmit the declaration group start to the inner class
variable.

Implements the strong mode proposal's restrictions on
implicit conversions for binary arithmetic operations, not
including the + special case. Adds some infrastructure
for future implementation of the restrictions for other
operators.

This introduces a bailout point for class literals right after the
%DefineClass function has been called. Otherwise the FrameState after
class literal evaluation might contain the literal itself.

Given
FunctionLiteral* a; a->is_parenthesized()
const FunctionLiteral* b; b->is_parenthesized()
the first accesses FunctionLiteral::IsParenthesized, the second accesses Expression::IsParenthesizedField.
Since these are distinct uses, we could rename them based on their use:
- Expression::is_parenthesized -> is_single_parenthesized
Count # of parenthesis, for parsing & error handling:
no parenthesis -> single parenthesis -> multi parenthesis
- FunctionLiteral::eager_compile_hint()
Hint from parser to compiler about whether the parser suggests this function for eager compilation.

A strict arrow function with no parameters and no variable bindings
won't need a context object because it will never have any
locals. (This is unlike strict normal functions, which do have
"arguments" and "this" locals.)
