Remove FrameLoaderClient::hasHTMLView, which always returns true.

Also, delete PlaceholderDocument, which will never be used because hasHTMLView
is always true.

Re-order members of a few WTF structures to put the pointers first. This minor
tidy-up is useful in two areas:
- Introduces the possibilty of better packing, although no specific packing
sitation is targeted here.
- Is of minor usefulness to security. Certain classes of corruptions will
trash only the first few bytes of an object. It's easiest to detect the
corruption earlier (e.g. in a crash dump) if a pointer is ruined, rather than
a length.
