We need to either create a directory using %t or build the output file as %t. %t is needed as all tests in this directory build into the same directory and %t will be a unique name for this test based off of the filename that contains the test.

Using %t:
```
// RUN: %clang_host -g -gsplit-dwarf -gpubnames -gdwarf-5 %s -o %t
// RUN: rm %t.dwo
// RUN: %lldb --no-lldbinit %t \
// RUN:   -o "b main" --batch 2>&1 | FileCheck %s
```

You will need to check the name of the .dwo file to ensure it is actually `%t.dwo`. If this isn't the case, you can create a directory using %t:
```
# RUN: rm -rf %t.compdir
# RUN: mkdir -p %t.compdir
# RUN: pushd %t.compdir
// RUN: %clang_host -g -gsplit-dwarf -gpubnames -gdwarf-5 %s -o main
// RUN: rm *.dwo
// RUN: %lldb --no-lldbinit main \
// RUN:   -o "b main" --batch 2>&1 | FileCheck %s
```
