committed: testsuite patches (11/14): Don't expect null pointer check elimination for target { keeps_null_pointer_checks }

[Joern Rennecke]

Tested for avr with --target_board=atmega128-sim and native on  
i686-pc-linuc-gnu.

Committed as obvious.

        * gcc.dg/tree-ssa/pr21090.c: Do vrp1 scan check only for
        target { ! keeps_null_pointer_checks }.
        * gcc.dg/tree-ssa/unreachable.c: Do optimized scan check only for
        target { ! keeps_null_pointer_checks }.
