If we are building under NOJUMPTRIE then we require that noper_next is the same as scan (our current position in the regex program). Once we have two or more consecutive such branches we can create a trie of the EXACT's contents and stitch it in place into the program. If the sequence represents all of the branches in the alternation we replace the entire thing with a single TRIE node.

If noper is a trieable nodetype then the branch is a possible optimization target. If we are building under NOJUMPTRIE then we require that noper_next is the same as scan (our current position in the regex program). Once we have two or more consecutive such branches we can create a trie of the EXACT's contents and stitch it in place into the program. If the sequence represents all of the branches in the alternation we replace the entire thing with a single TRIE node. Otherwise when it is a subsequence we need to stitch it in place and replace only the relevant branches.
