We now identify IBM's Clang-based XL compilers, which define `__ibmxl__`, as `XLClang` rather than `XL`. In order to support existing project code that checks for `XL`, add a policy whose OLD behavior is to present the compiler id as `XL` and whose NEW behavior is to present the compiler id as `XLClang` as we really detect it.

* IBM Clang-based XL compilers that define ``__ibmxl__`` now use the
