The generated localeCompare table now agrees with Node on spellings that
tie at the primary and secondary levels. "l·" and "L·" collate as one
unit, equal to U+0140 and U+013F, through a contraction table. Precomposed
characters take their decompositions' elements after the case weights are
assigned, so U+0130 equals I + U+0307. Ligatures whose spelled-out letters
tie with them (ij and ij) get the case weight Node places them at among
their first letter's case forms, and ligatures with their own secondary
(Æ) keep their own case. The generator's check now also compares every
covered character's decompositions, case forms and ligature spellings in
four contexts. A per-thread class table lets the lazy primary comparison
find characters that need element lists with one lookup.
