  Optimize padding in CachedRawResource

Reviewed by Alex Christensen.

CachedRawResource was 1104 bytes big, with 171 bytes of padding. Fix by
reordering data members in classes stored by value in CachedRawResource.
End result is a size of 1056 bytes, with 132 bytes of padding, so there
is more that can be done.
