Recommit "[BitcodeReader] Validate OpNum, before accessing Record array."
This recommits r365750 (git commit 8b222ecf2769ee133691f208f6166ce118c4a164)
Original message:
Currently invalid bitcode files can cause a crash, when OpNum exceeds
the number of elements in Record, like in the attached bitcode file.
The test case was generated by clusterfuzz: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=15698
