MAKE-INSTANCE specialized on CLASS instead of STANDARD-CLASS

[Nikodemus Siivola]

Reported by Stephen Wilson to sbcl-devel on 7/22/08:

We have:

 * (sb-mop::generic-function-methods #'make-instance)

 (#<STANDARD-METHOD MAKE-INSTANCE (SYMBOL) {93EB881}>
  #<STANDARD-METHOD MAKE-INSTANCE (CLASS) {93EB899}>)

The spec defines a primary method specialized to STANDARD-CLASS instead of
CLASS.

If we replace the specialization on CLASS with STANDARD-CLASS we either deprecate functionality (using MAKE-INSTANCE to allocate structures, etc), or we need to add more methods.

What does AMOP say about this?
