Otherwise those two tests fail when running ./x.py test with this target.

//@ ignore-llvm reads to me like it ignores the test when using the LLVM codegen backend, not when using the *-gnullvm targets.

I agree it's ambiguous but also in line with other ABIs. I'm open for suggestions though.

Personally I'd love if ignore statements were more precise, like //@ignore-abi llvm or //@ignore-os windows.

I feel like we should fix needs-dlltool instead, like, what's the point of needs-dlltool if the test still runs on a target without dlltools?

needs-dlltool seems to answer the question "is dlltool on the PATH", which is a different question than "will the target actually try to use dlltool". For gnullvm, it will not try to use dlltool, so the fact that there is one on the PATH is not particularly relevant.

For reference, the condition that decides whether to use dlltool or use llvm APIs directly to generate an import library is

rust/compiler/rustc_codegen_llvm/src/common.rs

Line 387 in f9b1614

target.vendor == "pc" && target.os == "windows" && target.env == "gnu" && target.abi.is_empty()

It looks like tests\run-make\raw-dylib-custom-dlltool fails similarly

I'd agree with this, we should extend needs-dlltool so that it isn't just "there is a dlltool" but "the target will use it", ignore-llvm seems like it is ignoring that codegen backend.

Tested only x86_64-pc-windows-gnullvm but the changes are simple enough.
