Item numbers are used in the finite state machine to represent
places that parsing can get to.
Precedence levels are recorded in the vectors sprec and rprec.
sprec records the precedence level of each symbol, rprec the
precedence level of each rule. rprecsym is the symbol-number of
the symbol in %prec for this rule (if any).
SPREC records the precedence level of each symbol.
Precedence levels are assigned in increasing order starting with 1
so that numerically higher precedence values mean tighter binding
