So the problem is that thunk is expanded on the adjusted decl but we
still keep the adjustments and later fail to apply them?
I guess we have two options:
1) force thunk expansion to happen on original decls (before cloning)
so the body ends up being same as for ordinary function
2) remove the adjustments after expansion - this should IMO work
under the assumption that optimization passes don't insert
non-trivial code into the thunk before they expand the thunk (i.e.
if you want to adjust it in ipa-sra you will want to first produce
the thunk and then do adjustement)
It seems to me that 2 should be not that hard to implement
Does that make sense?
