put into the CPP.Defines variable. Seems the convention was corrupted with
various changes made. It is important to get command line parameters into the

Initialize the IndexedModeActions array with memset before

updating it with calls to setIndexedLoadAction/setIndexedStoreAction,
which only update a few bits at a time. This avoids ostensible
undefined behavior of operationg on values which may be
trap-representations, and as a practical matter fixes errors from
valgrind, which doesn't track uninitialized memory with bit
granularity.
