-Force memory operands to be copied into registers before doing
-arithmetic on them.  This produces better code by making all memory
-references potential common subexpressions.  When they are not common
-subexpressions, instruction combination should eliminate the separate
-register-load. This option is now a nop and will be removed in 4.2.
