Item numbers are used in the finite state machine to represent
places that parsing can get to.
- SPREC records the precedence level of each symbol.
+ SYMBOLS[I]->PREC 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
