Subject: [PATCH] [IRGenDebugInfo] Replace llvm.dbg.coroframe_entry with
 dbg.declare_value

We had introduced coroframe_entry downstream while the upstream proposal
was discussed. It has since been merged upstream, so this commit changes
the code to use the upstream intrisic, avoiding a binary incompatibility
in the IR w.r.t. upstream.
