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

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

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
