The VMap also contains a mapping from Argument => Instruction, where the instruction is part of the original function, not the inlined one. The code was assuming that all the instructions in the VMap were inlined. This was a pre-existing problem for the loop access metadata, but was extended to the more common noalias metadata by 27f647d117087ca11959e232e6443f4aee31e966, thus causing miscompiles. There is a similar assumption inside CloneAliasScopeMetadata(), so that one likely needs to be fixed as well.
