reduced test case from Kokkos without template code
Not sure if this is a bug or what we expect, however, this asserts only happens
when `-fopenmp-targets` is set.
Command for running the code:
clang++ -fopenmp -fopenmp-targets=nvptx64 -emit-llvm -S no_template.cpp
```
Assertion failed: ((Record->hasTrivialCopyConstructor() ||
Record->hasTrivialCopyAssignment() || Record->hasTrivialMoveConstructor() ||
Record->hasTrivialMoveAssignment() || Record->isUnion()) && "Trying to
aggregate-copy a type without a trivial copy/move " "constructor or assignment
operator"), function EmitAggregateCopy, file
/Users/cchen/workspace/llvm-project/clang/lib/CodeGen/CGExprAgg.cpp, line 1950.
PLEASE submit a bug report to <a href="https://bugs.llvm.org/">https://bugs.llvm.org/</a> and include the crash
backtrace, preprocessed source, and associated run script.
