Revert [BitcodeReader] Validate OpNum, before accessing Record array. This reverts r365750 (git commit 8b222ecf2769ee133691f208f6166ce118c4a164) llvm-dis runs out of memory while opening invalid-fcmp-opnum.bc on llvm-hexagon-elf, probably because the bitcode file contains other suspicious values. http://lab.llvm.org:8011/builders/llvm-hexagon-elf/builds/21949 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@365757 91177308-0d34-0410-b5e6-96231b3b80d8 Florian Hahn a month ago
