Reduce HTMLAttachmentElement size by 8 bytes via field reordering
https://bugs.webkit.org/show_bug.cgi?id=318208
rdar://181009514
Reviewed by Chris Dumez.
m_implementation (Implementation, a uint8_t enum) was declared as the
first data member, immediately followed by m_file (RefPtr), so it sat
alone in its own 8-byte slot with 7 bytes of padding. The class already
has sub-word members at the tail (m_needsIconRequest and, under
ENABLE(SERVICE_CONTROLS), m_isImageMenuEnabled) that share a slot.
Move m_implementation down next to those bools so the small members pack
into a single 8-byte slot, shrinking HTMLAttachmentElement by 8 bytes.
m_implementation is only ever set via assignment, never in a constructor
initializer list, so declaration order is unaffected. No behavior change.
