compiler: free a string an expression made once it has been used

The left half of a + chain, a template's pieces and holes, a number's text and a side made only to be
compared are marked fresh and freed after the +, ==, != or print that reads them. lp_int_str and
lp_long_str move their digits to the start of the buffer, so the pointer they return is the one
malloc gave. Reseeded. examples/lang/string_temps.ludic: kept intermediates stay good, and 20,000
rounds grow the heap 0 bytes (2.9 MB before).
