rG8298ec2d6299: [flang][driver] Copy input files into a temp dir when testing
Summary

The following frontend driver invocation will generate 2 output files
in the same directory as the input files:

flang-new -fc1 input-1.f input-2.f

This is the desired behaviour. However, when testing we need to make
sure that we don't pollute the source directory. To this end, copy test
input files into a temporary directory.
