    convert_to_complex vs invalid_conversion [PR111903]

    convert_to_complex when creating a COMPLEX_EXPR does
    not currently check if either the real or imag parts
    was not error_mark_node. This later on confuses the gimpilfier
    when there was a SAVE_EXPR wrapped around that COMPLEX_EXPR.
    The simple fix is after calling convert inside convert_to_complex_1,
    check that the either result was an error_operand and return
    an error_mark_node in that case.

    Bootstrapped and tested on x86_64-linux-gnu with no regressions.

    gcc/ChangeLog:

            * convert.cc (convert_to_complex_1): Return
            error_mark_node if either convert was an error
            when converting from a scalar.

    gcc/testsuite/ChangeLog:

            * gcc.target/i386/float16-8.c: New test.
