rule: never merge across non-expression statements
commit 99ab1b8feb16741a83fb8b887bacae8fa07d29a2 upstream.
The existing logic can merge across non-expression statements,
if there is only one payload expression.
Example:
ether saddr 00:11:22:33:44:55 counter ether type 8021q
is turned into
counter ether saddr 00:11:22:33:44:55 ether type 8021q
which isn't the same thing.
Fix this up and add test cases for adjacent vlan and ip header
fields. 'Counter' serves as a non-merge fence.
