If an SSA is defined in the current block, there is no need to query
range_on_path_entry for additional information.
Tested on x86-64 Linux.
gcc/ChangeLog:
* gimple-range-path.cc (path_range_query::path_range_query):
Move debugging header...
(path_range_query::precompute_ranges): ...here.
(path_range_query::internal_range_of_expr): Do not call
range_on_path_entry if NAME is defined in the current block.
