RFA: testsuite patches (1/6): keeps_null_pointer_checks effect on pta/alias dump files

[Joern Rennecke]

On keeps_null_pointer_checks, relative to other targets, we see some NULLs in
sets replaced with/merged into NONLOCAL.
Tested for avr with --target_board=atmega128-sim and native on  
i686-pc-linuc-gnu.

Ok to apply?

        * gcc.dg/ipa/ipa-pta-14.c (scan-ipa-dump) [keeps_null_pointer_checks]:
        Don't expect NULL in foo.result set.
        * gcc.dg/tree-ssa/pta-escape-1.c (scan-tree-dump): Don't expect NULL
        in ESCAPED set.
        * gcc.dg/tree-ssa/pta-escape-2.c: Likewise.
        * gcc.dg/tree-ssa/pta-escape-3.c: Likewise.
