Yes but that would be even much larger patch than just converting CORE_ADDRs
in use as a displacement into the non-scalar.
It is true this "displacement-only-CORE_ADDRs" has missed some usages of
CORE_ADDR as a displacement. But it is enough to catch the variable/field
declaration over all the use points of it if it would be left as a scalar.
