a) avoid actually compiling anything
b) avoid depositing files in the test directory
c) use a check line to make sure that we're looking for the correct behavior

Currently the two flags can not work together.
To illustrate the issue, we can have an one line file a.cl contains only an empty function
cat a.cl
void test(){}
Then use
clang -v -save-temps -x cl -Xclang -cl-std=CL2.0 -Xclang -finclude-default-header -target amdgcn -S -c a.cl
we will get redefinition errors for various things.
The reason is that the -finclude-default-header flag is not meant to be on cc1 command other than the preprocessor.
The fix is modeled after the code just below the change to filter the -finclude-default-header flag out when we are not in the preprocess phase.
