John McCall 38dbb60675 Update SmallVector to support move semantics if the host does.
Note that support for rvalue references does not imply support
for the full set of move-related STL operations.

I've preserved support for an odd little thing in insert() where
we're trying to support inserting a new element from an existing
one.  If we actually want to support that, there's a lot more we
need to do:  insert can call either grow or push_back, neither of
which is safe against this particular use pattern.
