This currently fails. Unfortunately, we don't have Windows premerge CI, so you'll need to run the test manually.

The build script doesn't accept free arguments. I think you have to manually call clang and lld:
```
# REQUIRES: lld, target-windows, x86
# RUN: %clang_cl --target=x86_64-uefi -Z7 -c /Fo%t.obj -- %S/Inputs/relocatable.cpp
# RUN: lld-link -debug:full -subsystem:efi_application -nodefaultlib -noentry -dll %t.obj -out:%t.dll -pdb:%t.pdb
```

The resulting DLL will load with and without this PR. I'm guessing you already have some setup where you build a UEFI binary. Could you check if that uses some special linker flag?
