As suggested by:

This changes the type of the lr register from a pure integer type
to a code_ptr type.

        * power-core.xml, power64-core.xml, powerpc-601.xml, rs6000.xml:
        Change the type of the lr register to code_ptr.
        * powerpc-32.c, powerpc-403.c, powerpc-403gc.c, powerpc-505.c,
        powerpc-601.c, powerpc-602.c, powerpc-603.c, powerpc-604.c,
        powerpc-64.c, powerpc-7400.c, powerpc-750.c, powerpc-860.c,
        powerpc-e500.c, rs6000.c: Regenerate.

Tested on ppc-aix. No regression.
OK to apply?

Thanks,
