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.

Add class to existing lexical scoping tests

This patch strengthens testing of classes by verifying that the binding
that they export externally follows block scoping, as opposed to var-style
scoping. The tests are based on existing tests for let and const.

Security: disable nontemporals.

The operations were available on ARM64 and x86-32 but were unused.

It has been conjectured that nontemporals can be used for rowhammer-like bitflips more easily than regular load/store operations. It is therefore desirable to avoid generating these instructions in the future.

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.
