  Log Message:
  -----------
  [BuildLibCalls] Add argmemonly, writeonly, nounwind to memset_chk.

The memset_chk library function should match memset's attributes with
respect of memory effects (argmemonly, writeonly). It also does not
raise exceptions. It may not return, in case it aborts the program.
