Change the description of an operand x that has a named type of sorts
by providing a description of the type structure (array, struct, slice,
pointer, etc).
For instance, given a (variable) operand x of a struct type T, the
operand is mentioned as (new):
x (variable of struct type T)
instead of (old):
x (variable of type T)
This approach is also used when a basic type is renamed, for instance
as in:
x (value of uint type big.Word)
which makes it clear that big.Word is a uint.
This change is expected to produce more informative error messages.
Fixes#69955.
