[PATCH] IPA ICF fallout: disable IPA ICF for a test

[Martin Liška]

Hello.

In gcc.dg/tree-ssa/ldist-19.c, there's a pair of functions (one with 'char' and 
second with 'unsigned char'). These two functions are merged by IPA ICF on 
targets that where 'char' == 'unsigned char'. So that it would be easier to 
disable the optimization.

Ready for trunk?

Thanks,
Martin

        * gcc.dg/tree-ssa/ldist-19.c: ICF is disabled
        for the test because of default char signedness
        on powerpc64 target.
