Filter out slot buffer slots, that point to SMIs in dead objects.

The following situation may happen which reproduces this bug:
(1) We allocate JSObject A on an evacuation candidate.
(2) We allocate JSObject B on a non-evacuation candidate.
(3) Incremental marking starts and marks object A and B.
(4) We create a reference from B.field = A; which records the slot B.field since A is on an evacuation candidate.
(5) After that we write a SMI into B.field.
(6) After that B goes into dictionary mode and shrinks its original size. B.field is now outside of the JSObject, i.e B.field is in memory that will be freed by the sweeper threads.
(7) GC is triggered.
(8) BUG: Slots buffer filtering walks over the slots buffer, SMIs are not filtered out because we assumed that SMIs are just ignored when the slots get updated later. However, recorded SMI slots of dead objects may be overwritten by double values at evacuation time.
(9) During evacuation, a heap number that looks like a valid pointer is moved over B.field.
(10) The slots buffer is scanned for updates, follows B.field since it looks like a pointer (the double value looks like a pointer), and crashes.

[runtime] Remove useless %_IsUndetectableObject intrinsic.

Instead of using a sequence

if (something == null && !IS_UNDETECTABLE(something))) { ... }

which will be true if something is either null or undefined, it is
way simpler and way more efficient to just write

if (something === null || something === (void 0)) { ... }

instead, which allows the compiler(s) to generate pretty decent code
without any need to resort to type feedback from a CompareNil IC.

Do not save script object on the class constructor.

We don't need it, as we can grab it from the shared function info.
Having it triggers an assertion if we define classes in native JS.

[runtime] Simplify CHECK_OBJECT_COERCIBLE.

Don't use IS_NULL_OR_UNDEFINED() for CHECK_OBJECT_COERCIBLE() because it
will also return true for undetectable objects, but use IS_NULL() and
IS_UNDEFINED() directly, which will only return true for null or
undefined (which matches the semantics of the abstract operation
CheckObjectCoercible).

Remove inline header includes from non-inline headers (1).

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 7 violations of that rule in the
code. However there now is the "tools/check-inline-includes.sh" tool
detecting such violations.

Split function block scoping into a separate flag

In an initial attempt to implement sloppy mode lexical bindings,
functions were made lexically scoped in sloppy mode. However, the
ES2015 spec says that they need an additional hoisted var binding,
and further, it's not clear when we'll implement that behavior
or whether it's web-compatible.

This patch splits off function block scoping into a new, separate
flag called --harmony_sloppy_function. This change will enable the
possibility of testing and shipping this feature separately from
other block scoping-related features which don't have the same risks.

Use a new lexical context for sloppy-mode eval

In ES6, direct eval() in sloppy mode uses the enclosing function-level
("var") scope for var-style bindings and a new lexical scope for lexical
bindings like let and class. This patch implements that feature by making
lexical bindings that are directly within an EVAL_SCOPE be on the local
scope rather than the enclosing one.

[runtime] Store constructor function index on primitive maps.

This way we can greatly simplify the different variants of ToObject in
our codebase and make them more uniform and robust. Adding a new
primitive doesn't require finding and changing all those places again,
but it is sufficient to setup the constructor function index when
allocating the map.

We use the inobject properties field of Map, which is invalid primitive
maps anyway.
