I apparently forgot to update the clang and llvm patches before
they were committed for me with the new name of the compiler-rt library
supporting -fprofile-instr-generate=, which was changed during the review
process. This wasn't caught by this test as it doesn't link and is consistent
with the library call being inserted by llvm.
I want to temporarily revert this test so that it doesn't break when I make
the llvm change to call the correct library routine
(__llvm_profile_override_default_filename), then will send a patch to add itx
back with the correct name.
Tested via ninja clang-test
