Thanks.  Allow me a couple of minor comments.

For us to be able to bind M-u etc. to these new commands, they need to
support the prefix argument to upcase-word etc.  The way you wrote
these new commands, that feature will be lost.

Every doc string should state the effect of the function/variable in
its first line, because some Help commands (like 'apropos') show only
the first line.  The above doc string (and the others in your patch)
don't do that; the effect is only clear if one reads the rest of the
doc string.

I suggest to change the doc strings like this:

  Upcase words in the region, if active; otherwise upcase word at point.
If the region is active, this function calls `upcase-region'.
Otherwise it calls `upcase-word'.
