* tree-scalar-evolution.c (get_scalar_evolution): Handle
default-defs and types we do not want to analyze.
(interpret_loop_phi): Replace unreachable code with an assert.
(compute_scalar_evolution_in_loop): Remove and inline ...
(analyze_scalar_evolution_1): ... here, replacing condition with
what makes the intent clearer. Remove handling of cases
get_scalar_evolution now handles.
