Summary:
We would like the UMR debugging tool[0] to be able to provide
disassembly for currently live waves based on plain memory
dumps, and we want to leverage the LLVM disassembler for this.
This mostly works, except that UMR clearly can't provide real
symbol info, so it wants to set DisInfo == nullptr.
