* cse.c: Change encoding of quantity numbers to avoid undefined
pointer arithmetic on qty_table.
(REGNO_QTY_VALID_P): A quantity is now valid if it isn't negative.
(get_cse_reg_info): Initialize reg_qty to a unique negative value.
(new_basic_block): Assign "real" quantity numbers from zero.
(delete_reg_equiv): Do nothing if quantity is invalid. Reset the
REG_QTY to its unique negative value.
(merge_equiv_classes): Calculate need_rehash if quantity is valid.
(cse_main): Don't include max_reg when determining max_qty.
(cse_basic_block): Avoid subtracting a large offset from qty_table,
which causes undefined C99 behaviour. Only allocate needed memory.
