Account for multi-dfa case with ANCHORED_DELAY

Browse Source 
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.
