[PATCH] D134441: [ObjC][ARC] Don't use operand bundle "clang.arc.attachedcall" in codegen for Windows

[Stefan Gränitz via Phabricator via cfe-commits]

sgraenitz added a comment.

The symptom is that Clang emits `movq %rax, %rdi` instead of `movq %rax, %rcx` while `objc_retainAutoreleasedReturnValue()` still expects the value in `%rcx`.
It appears related to D94597 <https://reviews.llvm.org/D94597>. Is this a calling convention issue?
