grammar-l11: remove left-recursion
In the original change, the EXP in PROD-EXP should have been PROD-EXP, similarly EXP in SINGLE-EXP should have been SINGLE-EXP. Otherwise the operator precedence is not applied correctly (consider 1+2*3, it should be interpreted as 1+(2*3), not (1+2)*3). Anyway, this change removes left-recursion as described in 2.12.1.
