[PATCH] {master} Useless precedence warning

[Valentin Tolmer]

This patch records used precedence relationships between symbols and warns the
user about useless ones. Symbols with associativity are ignored as it is
currently impossible to declare associativity without declaring precedence.

  grammar: warn about unused precedence for symbols
