scheme, we can switch the previous scheme over to using this code
path.  There's a bit of simplifications yet to do as well.

"usual deallocation function" with two arguments. CodeGen will have to
handle this case specifically, since the value for the second argument
(the size of the allocated object) may have to be computed at run

Type hierarchy.  Demote 'volatile' to extended-qualifier status.  Audit our
use of qualifiers and fix a few places that weren't dealing with qualifiers
quite right;  many more remain.
