[SYCL] Clang Driver ICE when no input file found

[agozillon]

I get an ICE at the moment when I compile using the following command and the file is not found:

$ISYCL_BIN_DIR/clang++ -std=c++11 -fsycl no_file.cpp -o no_file -lOpenCL

I've added the stack dump at the bottom if that's of any use.

If I remove the -lOpenCL component, I do not recieve a stack dump and get the desired output:

$ISYCL_BIN_DIR/clang++ -std=c++11 -fsycl no_file.cpp -o no_file

clang-9: error: no such file or directory: 'no_file.cpp'
clang-9: error: no input files

This may be something you guys have already noticed unless it's an environment or understanding problem on my end? Hopefully it's not a user error on my part in this case, if it is I apologize.

@agozillon, I can't reproduce this issue using the latest version of the compiler.
Could you confirm that it's fixed on your side too, please?

[agozillon]

Works fine on my end as well, happy to close the issue
