segtree: refactor decomposition of closed intervals

Move the code in `interval_map_decompose` which adds a new closed
interval to the set into a separate function.  In addition to the moving
of the code, there is one other change: `compound_expr_add` is called
once, after the main conditional, instead of being called in each
branch.
