use more get_range_query
For "get_global_range_query" SSA_NAME_RANGE_INFO can be queried.
For "get_range_query", it could get more context-aware range info.
And look at the implementation of "get_range_query", it returns
global range if no local fun info.
So, if not quering for SSA_NAME and not chaning the IL, it would
be ok to use get_range_query to replace get_global_range_query.
gcc/ChangeLog:
* fold-const.cc (expr_not_equal_to): Replace get_global_range_query
by get_range_query.
* gimple-fold.cc (size_must_be_zero_p): Likewise.
* gimple-range-fold.cc (fur_source::fur_source): Likewise.
* gimple-ssa-warn-access.cc (check_nul_terminated_array): Likewise.
* tree-dfa.cc (get_ref_base_and_extent): Likewise.
