RFR (XS) 8252290: C2: Remove unused enum in CallGenerator

[Reingruber, Richard]

Hi Aleksey,

the cleanup looks good to me.

That enum was already part of the initial load with xxxunusedxxx as the only element [1].
So there's no open version history.

I could not find any references either (rtags, grep). Probably the enum had more elements
originally which were removed.

Thanks, Richard.

Static code inspection complains the enum below is unused.
