re PR tree-optimization/82381 (internal compiler error: qsort checking failed)

PR tree-optimization/82381
* tree-ssa-reassoc.c (sort_by_operand_rank): Don't check
stmt_to_insert nor wheather SSA_NAMEs are default defs.
Return 1 or -1 if one of bba and bbb is NULL. If bb_rank is equal,
fallthrough into reassoc_stmt_dominates_stmt_p.

* gcc.c-torture/compile/pr82381.c: New test.
