path solver: Prefer range_of_expr instead of range_on_edge.
The range_of_expr method provides better caching than range_on_edge.
If we have a statement, we can just it and avoid the range_on_edge
dance. Plus we can use all the range_of_expr fanciness.
Tested on x86-64 and ppc64le Linux with the usual regstrap. I also
verified that the before and after number of threads was the same or
greater in a suite of .ii files from a bootstrap.

PR tree-optimization/102943
* gimple-range-path.cc (path_range_query::range_on_path_entry):
Prefer range_of_expr unless there are no statements in the BB.
