* sources/dfmc/modeling/functions.dylan
  (&class <profiling-call-site-cache-header-engine-node>): Declare the

   <raw-machine-word> to reflect the way they are used in generated code.

* sources/dfmc/llvm-back-end/llvm-entry-points.dylan
  (entry-point-descriptor profiling-cache-header): Remove a "todo"
   comment about making the change above.

* sources/dylan/discrimination.dylan
  (compute-terminal-engine-node): Change the initialization order of
   profiling cache header engine nodes so that the generic function
   is available to the primitive-initialize-engine-node implementation
   (via the cache-header-engine-node-parent slot).

* sources/dylan/new-dispatch.dylan
  (make-linear-class-keyed-discriminator): Initialize lckd-hits
   in newly instantiated <linear-class-keyed-discriminator> nodes.
  (linear-class-key-lookup): Increment lckd-hits when the class is
   found.
  (make-linear-singleton-discriminator): Initialize lsd-hits in newly
   instantiated <linear-singleton-discriminator> nodes.
  (immediate-linear-singleton-discriminator-element): Increment
   lsd-hits when the matching instance is found.
  (value-object-linear-singleton-discriminator-element): Increment
   lsd-hits when the matching instance is found.

* sources/lib/dispatch-profiler/dispatch-profiler.dylan
  (with-dispatch-profiling-report): New macro for performing dynamic
   dispatch profiling on a block of code and printing out a summary
   report after execution completes.

* sources/lib/dispatch-profiler/dispatch-profiler-library.dylan
  (module dispatch-profiler): Export the
   with-dispatch-profiling-report macro.

* documentation/source/library-reference/dispatch-profiler/index.rst:
  New documentation source.
