Bjorn Steinbrink 6eaa62af77 Allow call-slop optzn for destinations with a suitable dereferenceable attribute ... Summary: Currently, call slot optimization requires that if the destination is an argument, the argument has the sret attribute. This is to ensure that the memory access won't trap. In addition to sret, we can also allow the optimization to happen for arguments that have the new dereferenceable attribute, which gives the same guarantee.
