Add functions to find the matching ELSE, ENDIF expressions

ExpressionId FindMatchingEndif(ExpressionId id)
   - Finds the closing ENDIF expression for a given IF expression.

ExpressionId FindMatchingElse(ExpressionId id)
   - Finds the ELSE expression for a given IF expression.
   - Returns -1, if this IF doesn't have an else

This patch is a preparation to the code analyzing required
for various optimization passes.

Ceres Solver

Ceres Solver is an open source C++ library for modeling and solving large, complicated optimization problems. It is a feature rich, mature and performant library which has been used in production at Google since 2010. Ceres Solver can solve two kinds of problems.

  1. Non-linear Least Squares problems with bounds constraints.
  2. General unconstrained optimization problems.
