This change corrects how the mode for masked cbranch operands is determined. Previously, it used GET_MODE on an expanded masked operation, which could incorrectly result in VOIDmode for vector boolean constants. The fix adjusts this to use TYPE_MODE of the operand, ensuring constants are materialized in the correct mask mode and preventing an assertion failure.
