* tree-ssa-reassoc.c (rewrite_expr_tree_parallel): Insert assert
that would prevent us to call alloca with -1 as argument.
Maybe one day we'll be able to use the array index into STMTS to derive
a range for stmt_num. But we don't right now.
Otherwise I don't see any way to derive a range for stmt_num that if
rewrite_expr_tree_parallel is not inlined into its caller.
OK for the trunk.
