    lower-bitint: Fix a typo in a condition [PR113323]

    The following testcase revealed a typo in condition, as the comment
    says the intent is
           /*  If lhs of stmt is large/huge _BitInt SSA_NAME not in m_names
               it means it will be handled in a loop or straight line code
               at the location of its (ultimate) immediate use, so for
               vop checking purposes check these only at the ultimate
               immediate use.  */
    but the condition was using != BITINT_TYPE rather than == BITINT_TYPE,
    so e.g. it used bitint_precision_kind on non-BITINT_TYPEs (e.g. on vector
    types it will crash because TYPE_PRECISION means something different there,
    or on say INTEGER_TYPEs the precision will never be large enough to be >=
    bitint_prec_large).

    The following patch fixes that.
