[dev.typeparams] cmd/compile: set Func.ClosureCalled in escape analysis
The Func.ClosureCalled flag is an optimization used by escape analysis
to detect closures that were directly called, so we know we have
visibility of the result flows. It's not needed by any other phases of
the compiler, so we might as well calculate it within escape analysis
too.
This saves some trouble during IR construction and trying to maintain
the ClosureCalled flag through inlining and copying.
Passes toolstash -cmp.
