Store 1 in DO_NOT_RECORD_P if any subexpression is volatile.
If HASH_ARG_IN_MEMORY_P is not NULL, store 1 in it if X contains
- a MEM rtx which does not have the RTX_UNCHANGING_P bit set.
+ a MEM rtx which does not have the MEM_READONLY_P flag set.
Note that cse_insn knows that the hash code of a MEM expression
is just (int) MEM plus the hash code of the address. */
