    i386: Fix expand_vector_set for VEC_MERGE/VEC_DUPLICATE RTX [PR117116]

    Middle end can generate SYMBOL_REF RTX as a value "val" in the call
    to expand_vector_set, but SYMBOL_REF RTX is not accepted in
    <sse2p4_1>_pinsr<ssemodesuffix> insn pattern, generated via
    VEC_MERGE/VEC_DUPLICATE RTX path.

    Force the value into a register before VEC_MERGE/VEC_DUPLICATE RTX
    is generated if it doesn't satisfy nonimmediate_operand predicate.

            PR target/117116

    gcc/ChangeLog:

            * config/i386/i386-expand.cc (expand_vector_set): Force "val"
            into a register before VEC_MERGE/VEC_DUPLICATE RTX is generated
            if it doesn't satisfy nonimmediate_operand predicate.

    gcc/testsuite/ChangeLog:

            * gcc.target/i386/pr117116.c: New test.
