1.0.29.41: inline CTOR caches for MAKE-INSTANCE

* If MAKE-INSTANCE has constant keywords but a variable first argument,
  build an inline cache of CTORs.

  ** Initially a sorted list, switching to a max 256 entry table if
     the list grows too large.

  ** Rename CTOR-NAME to CTOR-NAME-OR-CLASS, and allow building CTORs
     for class arguments as wel. Similarly, CTOR function names
     can contain class objects as well.

  ** Factor out RANDOMLY-PUNTING-LAMBDA from cache.lisp, since CTOR
     cache wants it too.

  ** STD-INSTANCE-P and FSC-INSTANCE-P become functions with compiler
     macros -- they are now used in compiler-support.lisp, which
     is built before low.lisp, so using macros is out.

* Also enable the existing CTOR optimization for constant class objects
  as class arguments.

* Tests.
