c: Don't warn about converting NULL to different sso endian [PR104822]
In a similar way we don't warn about NULL pointer constant conversion to
a different named address we should not warn to a different sso endian
either.
This adds the simple check.
Bootstrapped and tested on x86_64-linux-gnu with no regressions.
PR c/104822
gcc/c/ChangeLog:
* c-typeck.cc (convert_for_assignment): Check for null pointer
before warning about an incompatible scalar storage order.
gcc/testsuite/ChangeLog:
* gcc.dg/sso-18.c: New test.
* gcc.dg/sso-19.c: New test.
