re PR tree-optimization/91157 (ICE: verify_gimple failed (error: position plus size exceeds size of referenced object in 'bit_field_ref'))

	PR tree-optimization/91157
	* tree-vect-generic.c (expand_vector_comparison): Handle lhs being
	a vector boolean with scalar mode.
	(expand_vector_condition): Handle first operand being a vector boolean
	with scalar mode.
	(expand_vector_operations_1): For comparisons, don't bail out early
	if the return type is vector boolean with scalar mode, but comparison
	operand type is not.

	* gcc.target/i386/avx512f-pr91157.c: New test.
	* gcc.target/i386/avx512bw-pr91157.c: New test.
