The test would fail with `-filetype=obj`. llvm/lib/Target/AArch64/AArch64MCInstLower.cpp:80 `Printer.OutStreamer->emitAssignment` calls `setVariableValue`, which has an assertion that `SymbolContents` must be SymContentsUnset/SymContentsVariable.
However, when using MCObjectStreamer, the SymbolContents would be SymContentsOffset.
```
% myllc -mtriple=arm64ec-pc-windows-msvc -arm64ec-generate-thunks=false < CodeGen/AArch64/arm64ec-varargs.ll -filetype=obj
llc: /home/ray/llvm/llvm/lib/MC/MCSymbol.cpp:52: void llvm::MCSymbol::setVariableValue(const MCExpr *): Assertion `(SymbolContents == SymContentsUnset || SymbolContents == SymContentsVariable) && "Cannot give common/offset symbol a variable value"' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.
