ranger: Add range-ops for widen addition and widen multiplication [PR108583]
This adds range-ops for widening addition and widening multiplication.
I couldn't figure out how to write a test for this. It looks like there are
self tests but not a way to write standalone ones? I did create testcases in
the patch 3/4 which tests the end result.
gcc/ChangeLog:
PR target/108583
* gimple-range-op.h (gimple_range_op_handler): Add maybe_non_standard.
