    middle-end: Fix stalled swapped condition code value [PR115836]

    emit_store_flag_1 calculates scode (swapped condition code) at the
    beginning of the function from the value of code variable.  However,
    code variable may change before scode usage site, resulting in
    invalid stalled scode value.

    Move calculation of scode value just before its only usage site to
    avoid stalled scode value.

    gcc/ChangeLog:

            * expmed.cc (emit_store_flag_1): Move calculation of
            scode just before its only usage site.
