description:
lint: make the debug log for nodes more readable

The operator NAME has the name 'name', therefore no special case is
needed.

Having the words 'with type' in the message makes the message easier to
find from the debug log.  Given that the operator name is used unquoted,
the log message 'name: int value=111' was nearly impossible to find in
the code.

Replace the '()' with an actual word, to avoid any confusion about
whether the type name might be a function type without prototype.

Reduce the amount of '=' signs, instead use commas to separate the
properties of the node.

No functional change outside debug mode.
