Provide support for copying unsupported ranges.
The unsupported_range class is provided for completness sake. It is a
way to set VARYING/UNDEFINED ranges for unsupported ranges (currently
anything not float, integer, or pointer). You can't do anything with
them, except set_varying, and set_undefined. We will trap on any
other operation.
This patch provides a way to copy them, just in case they creep in.
This could happen in IPA under certain circumstances.
gcc/ChangeLog:
* value-range.cc (vrange::operator=): Add a stub to copy
unsupported ranges.
* value-range.h (is_a <unsupported_range>): New.
(Value_Range::operator=): Support copying unsupported ranges.
