r0-89280-g129a37fc319db8 added unsharing to remap_ssa_name but
that wasn't in the version of the patch posted. That has some
non-trivial cost through mostly_copy_tree_r and copy_tree_r but
more importantly it doesn't seem to be necessary. I've successfully
bootstrapped and tested with an assert we only get
tree_node_can_be_shared trees here.
Bootstrapped and tested on x86_64-unknown-linux-gnu with all
languages.
Pushed to trunk.
