updated; confirmed issue manifests in LLVM 11 and backtraces to ZigLLVMTargetMachineEmitToFile

So what this means is that it is indeed likely an LLVM bug, but not eligible to be a release blocker for LLVM 12.

Reproduce with:

$ ~/local/llvm14-debug/bin/clang -c reduced.ll -O2
clang: /home/andy/Downloads/llvm-project-13/llvm/lib/CodeGen/AsmPrinter/DwarfDebug.cpp:319: void llvm::DbgVariable::addMMIEntry(const llvm::DbgVariable&): Assertion `(FrameIndexExprs.size() == 1 || llvm::all_of(FrameIndexExprs, [](FrameIndexExpr &FIE) { return FIE.Expr && FIE.Expr->isFragment(); })) && "conflicting locations for variable"' failed.

Upstream issue: https://github.com/llvm/llvm-project/issues/56418

Does not occur with stage2.

This only affected stage1 and is therefore resolved by e7d28344fa3ee81d6ad7ca5ce1f83d50d8502118. Test coverage in std/json/test.zig.
