* Set the CORINFO_EH_CLAUSE_SAMETRY on CORINFO_EH_CLAUSE

This change makes setting the `CORINFO_EH_CLAUSE_SAMETRY` on
`CORINFO_EH_CLAUSE` to happen for coreclr to. It is a prerequisity for the
port of exception handling from nativeaot to coreclr and it is a noop on
coreclr with the old exception handling.
