What makes you say there are a lot round-trips through parse- and
unparse-type? Grepping the source we code, we can find two usages of
unparse-type: (1) the make-load-form method for foreign-type and (2)
some foreign-array-type code.

(2) shouldn't be there and it's got a FIXME nearby. (1) is why
unparse-type was introduced. Instances of foreign-type can end up in
fasls after various macros and compiler macros kick in and so we need
a way to serialize them.
