-380: Accessor redefinition fails because of old accessor name
- When redefining an accessor, SB-PCL::FIX-SLOT-ACCESSORS may try to
- find the generic function named by the old accessor name using
- ENSURE-GENERIC-FUNCTION and then remove the old accessor's method in
- the GF. If the old name does not name a function, or if the old name
- does not name a generic function, no attempt to find the GF or remove
- any methods is made.
-
- However, if an unrelated GF with an incompatible lambda list exists,
- the class redefinition will fail when SB-PCL::REMOVE-READER-METHOD
- tries to find and remove a method with an incompatible lambda list
- from the unrelated generic function.

- 18c does the same thing. RECOGNIZE-KNOWN-CALL correctly picks up only
- one of the calls, but local call analysis fails to inline the call
- for the second time. Nikodemus thinks (but is not 100% sure based on
- very brief investigation) that the call that is not inlined is the
- second nested one. A trivial fix is to call CHANGE-REF-LEAF in known
- call for functions already inline converted there, but he is not sure
- if this has adverse effects elsewhere.
