I've checked in these tweaks for various testcases that fail on
nios2-elf without an explicit -fdelete-null-pointer-checks option. This
target is configured to build with that optimization off by default.

Testsuite: Make dependence on -fdelete-null-pointer-checks explicit
nios2-elf target defaults to -fno-delete-null-pointer-checks, breaking
tests that implicitly depend on that optimization. Add the option
explicitly on these tests.
