tests: pacify gcc -fanalyzer on zerosize_ptr * tests/test-memcasecmp.c (main): * tests/test-memchr.c (main): * tests/test-memchr2.c (main): * tests/test-memcmp.c (main): * tests/test-memmem.c (main): * tests/test-memrchr.c (main): * tests/unistr/test-chr.h (main): * tests/unistr/test-cmp.h (test_cmp): Check whether zerosize_ptr returns NULL before using it. This pacifies GCC 10.1’s new fanalyzer option, and matches other uses of zerosize_ptr.
