Summary: This change consolidates the always/never lists that may be provided to clang to externally control which functions should be XRay instrumented by imbuing attributes. The files follow the same format as defined in https://clang.llvm.org/docs/SanitizerSpecialCaseList.html for the sanitizer blacklist. We also deprecate the existing `-fxray-instrument-always=` and `-fxray-instrument-never=` flags, in favour of `-fxray-attr-list=`. This fixes http://llvm.org/PR34721.
