    forwprop: Remove incorrect assertion [PR102897]

    As PR102897 shows, there is one incorrect assertion in function
    simplify_permutation, which is based on the wrong assumption that
    all cases with op2_type == tgt_type are handled previously, the
    proposed fix is to remove the assertion.

    gcc/ChangeLog:

            PR tree-optimization/102897
            * tree-ssa-forwprop.c (simplify_permutation): Remove a wrong
assertion.

    gcc/testsuite/ChangeLog:

            * gcc.dg/pr102897.c: New test.
