Change tree-parloops.c reduction and name_to_copy hash tables from
htab_t to hash_table.
Fold reduction_info_hash and reduction_info_eq into new struct
reduction_hasher. Fold name_to_copy_elt_eq and name_to_copy_elt_hash
into new struct name_to_copy_hasher.
Update dependent types and calls.
Tested on x86_64.
Okay for branch?
