    Previously the `INTERPROCEDURAL_OPTIMIZATION` target property was
    honored only for the Intel compiler on Linux and otherwise ignored.  In
    order to add support for more compilers incrementally without changing
    behavior in the future, add a new policy whose NEW behavior enforces the
    `INTERPROCEDURAL_OPTIMIZATION` property.  Add flags for supported
    compilers and otherwise produce an error.
