    IBM Z: Fix PR102222

    Avoid emitting a strict low part move if the insv target actually
    affects the whole target reg.

    gcc/ChangeLog:

            PR target/102222
            * config/s390/s390.c (s390_expand_insv): Emit a normal move if it
            is actually a full copy of the source operand into the target.
            Don't emit a strict low part move if source and target mode match.

    gcc/testsuite/ChangeLog:

            * gcc.target/s390/pr102222.c: New test.
