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.
Specifically, we must set build_context::floatingMinLiteralMatchOffset
to 1 when thew anchored table contains multiple DFAs, as they can
produce unordered matches.
This check was already been done, but too late to affect the generation
of ANCHORED_DELAY instructions.
