object file triggering linker error
When linking a code (single unit) compiled OpenMP target=amdgcn-amd-amdhsa with
trunk got the following ICE:
```

llvm::TargetLoweringBase::getRegClassFor(llvm::MVT, bool) const: Assertion `RC
&& "This value type is not natively supported!"' failed.
PLEASE submit a bug report to <a href="https://bugs.llvm.org/">https://bugs.llvm.org/</a> and include the crash
backtrace.
