Rose: use program for all literal matches

Unifies all literal match paths so that the Rose program is used for all
of them. This removes the previous specialised "direct report" and
"multi direct report" paths. Some additional REPORT instruction work was
necessary for this.

Reworked literal construction path at compile time in prep for using
program offsets as literal IDs.

Completely removed the anchored log runtime, which is no longer worth
the extra complexity.
