Empty reflected attributes and string literals in extended attributes.

Encoding the CORS setting attribute

  http://www.whatwg.org/specs/web-apps/current-work/#cors-settings-attribute

as a reflected attribute exposed a missing piece in our reflected
attribute handling: attributes that are empty (no value) can
separately be mapped to an attribute state. Upon reflection via its
IDL attribute, that state must then be mapped to its canonical
value/keyword.

Support the expression of this through the setting of
[ReflectEmpty="value"].

Separately, but also induced by CORS attributes, an attribute value
may contain non-identifier characters (as defined by WebIDL), which
makes identifiers not a perfect fit for specifying these reflected
attribute values (the use of "-" being the direct problem for CORS
attribute values.)

To address, extended attributes can now take string literals on their
right hand sides (e.g., [Attr="B"|"C"|"D"].) Attribute value lists
provided with [ReflectOnly=<list>] can then contain the wider range of
characters.

To go with that, the [ReflectEmpty], [ReflectMissing] and
[ReflectInvalid] attributes can also be given string literals on their
right hand side, e.g.,

  [ReflectEmpty="Value1", ReflectInvalid="Value2"]

The string literal must match one of the values in the [ReflectOnly]
list.

Move finalizeAll from the blink heap infrastructure branch to trunk.

Move over more tests from the branch to trunk.

Some of the tests are slightly modified and contain FIXMEs to
remember to bring them back to what they should be once we have
conservative stack scanning.

Update CSS classes to use OVERRIDE / FINAL when needed

Update CSS classes to use OVERRIDE / FINAL when needed. Those are useful for
error checking or performance when the compiler supports it.
