Change test/CodeGenCXX/debug-info-method.cpp an IR (rather than asm) test.

Referring back to the original commit (r115090) which was a frontend only test
I adjusted this test to verify the frontend change that was made, to emit the
protected access value in the flags metadata field.

Emit debug info for unnamed parameters.

LLVM ignores this data for now - patch for that to follow.
