Than McIntosh ea69de9b92 cmd/compile: rework marking of dead hidden closure functions
[This is a roll-forward of CL 484859, this time including a fix for
issue #59709. The call to do dead function marking was taking place in
the wrong spot, causing it to run more than once if generics were
instantiated.]

This patch generalizes the code in the inliner that marks unreferenced
hidden closure functions as dead. Rather than doing the marking on the
fly (previous approach), this new approach does a single pass at the
end of inlining, which catches more dead functions.
