Rose: Move all literal operations into program

Replace the RoseLiteral structure with more program instructions; now,
instead of each literal ID leading to a RoseLiteral, it simply has a
program to run (and a delay rebuild program).

This commit also makes some other improvements:

 * CHECK_STATE instruction, for use instead of a sparse iterator over a
   single element.
 * Elide some checks (CHECK_LIT_EARLY, ANCHORED_DELAY, etc) when not
   needed.
 * Flatten PUSH_DELAYED behaviour to one instruction per delayed
   literal, rather than the mask/index-list approach used before.
 * Simple program cache at compile time for deduplication.
