re PR rtl-optimization/12322 (Significant slowdown when compiling computed-goto code in Parrot)
PR optimization/12322
* gcse.c (struct ls_expr): Change type of hash_index from int to
unsigned int.
(hash_expr): Document hash_table_size parameter and wrap long line.
(ldst_entry): Calculate expression's hash_index and record in ptr.
(trim_ld_motion_mems): Use hash_index to search a single bucket
instead of scanning the entire hash_table. Remove the "del" local
variable and use the equivalent "expr == 0" instead. Change last
to be a pointer to the pointer to the current element, to simplify
and speed-up deleting from a linked list.
