Revert [BitcodeReader] Validate OpNum, before accessing Record array.

Browse Source 
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.
