I think you're right -- the patch is broken.  It should check
TREE_ADDRESSABLE, too, for the inlined parameter.  Wouldn't that
resolve that issue?  Removing these VAR_DECLs is a big win for memory
usage

I remember your other patch -- but not how it worked.  If you have it
handy, would you post it again?  I think maybe it does something
orthogonal: that both patches are good ideas.  Or do you think mine is
a bad idea, assuming the TREE_ADDRESSABLE thing gets fixed?
