unknown cdc382e7fd Bug#22312 Syntax error in expression with INTERVAL() ...

Parser rejects valid INTERVAL() expressions when associated with
arithmetic operators. The problem is the way in which the expression
and interval grammar rules were organized caused shift/reduce conflicts.

The solution is to tweak the interval rules to avoid shift/reduce
conflicts by removing the broken interval_expr rule and explicitly
specify it's content where necessary.

Original fix by Davi Arnaut, revised and improved rules by Marc Alff
