    analyzer: fix ICE on strlen ((char *)&VECTOR_CST) [PR111361]

    gcc/analyzer/ChangeLog:
            PR analyzer/111361
            * region-model.cc (svalue_byte_range_has_null_terminator_1): The
            initial byte of an all-zeroes SVAL is a zero byte.  Remove
            gcc_unreachable from SK_CONSTANT for constants that aren't
            STRING_CST or INTEGER_CST.

    gcc/testsuite/ChangeLog:
            PR analyzer/111361
            * c-c++-common/analyzer/strlen-pr111361.c: New test.
            * c-c++-common/analyzer/strncpy-1.c (test_zero_fill): Remove fi=
xed
            xfail.
            * c-c++-common/analyzer/strncpy-pr111361.c: New test.
