There are scenarios where mutually recursive functions may cause the SCC to contain both read only and write only functions. This removes an assertion when adding read attributes which caused a crash with a the provided test case, and instead just doesn't add the attributes. Patch by Luke Lau <luke.lau@intel.com> Differential Revision: https://reviews.llvm.org/D60761 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@366090 91177308-0d34-0410-b5e6-96231b3b80d8
