[bv-dev] Name for path nodes representing return values

[Emmanuel Bernard]

I am not a big fan of the retval which reminds me of Gollum skeaping his
name ;)

- <return value>
- <return>
- (return value)
- (return)

I think I like <return value> the best.

As Hardy said, the name is not critical as nodes are identified by their
elementDescriptor.kind.
