Enhance initial global value setting.

Incorporate code from vr_values to get safe initial parameter values.
If this is a local automatic which is used before defined, use UNDEFINED.

* gimple-range.h (gimple_range_global): Pick up parameter initial
values, and use-before defined locals are UNDEFINED.
