[Description]
Checks for symmetry.

[Explanation]
is_symmetric returns <A HREF="$$LINK(alloc.h/Bool)">TRUE</A> if the expression pointed to by
<I>expr_ptr</I> is such that it remains the same when the variable pointed to by
<I>var_ptr</I> changes its sign, otherwise it returns <A HREF="$$LINK(alloc.h/Bool)">FALSE</A>.
