This commit is largely cosmetic in the sense that it is the remnants
of a change proposal I had prepared for testing/quick, until I
discovered that 3e9ed273 already implemented the feature I was looking
for: quick.Value() for reflect.Kind Array.  What you see is a merger
and manual cleanup; the cosmetic cleanups are as follows:

(1.) Keeping the TestCheckEqual and its associated input functions
in the same order as type kinds defined in reflect.Kind.  Since
3e9ed273 was committed, the test case began to diverge from the
constant's ordering.

(2.) The `Intptr` derivatives existed to exercise quick.Value with
reflect.Kind's `Ptr` constant.  All `Intptr` (unrelated to `uintptr`)
in the test have been migrated to ensure the parallelism of the
listings and to convey that `Intptr` is not special.

(3.) Correct a misspelling (transposition) of "alias", whereby it is
named as "Alais".
