There're 2 occurrences where unqualified calls are always safe.
Always use `_STD_VECTORIZE_WITH_FLOAT_CONTROL` guards around `_Plus_on_arithmetic_ranges_reduction_v` and `_Default_ops_transform_reduce_v` machinery, drop their `false` fallbacks (which were weird and non-conventional). Use arrow comments for consistency. `_STD` qualify two more calls to `_Reduce_plus_arithmetic_ranges` in `<execution>`.

Separated from #4004 (this is the last one). Towards #1596.
Some
begin()calls are replaced withdata()because the iterator operations are not ADL-proof.begin()calls on_Parallel_vectorthat are not dependent on user-defined types and thus are always safe. I'm not sure whether we should consistently usedata()(which possibly improves debug performance).After merging this PR, there're still a small number of unqualified
_Adl_verify_rangecalls that possibly do evil (inspananddistanceetc.).The remaining unqualified
_Adl_verify_rangecalls looks "OK" to me as ADL-incompatible types don't seem required to be supported in those cases (where the acceptable value types are integer/character types).
