[PATCH] vr-values: Avoid ICEs on large _BitInt cast to floating point [PR112901]

Hi! For casts from integers to floating point, simplify_float_conversion_using_ranges uses SCALAR_INT_TYPE_MODE and queries optabs on the optimization it wants to make. That doesn't really work for large/huge BITINT_TYPE, those have BLKmode which is not scalar int mode. Querying an optab is not
