remove obsolete conversion handling from vectorizable_assignment

Browse source 
This removes an odd special-case of VECTOR_BOOLEAN_TYPE_P typed
conversions from vectorizable_assignment that was obsoleted by
making all integer mode VECTOR_BOOLEAN_TYPE_P types have 1-bit
precision bool components with 605c2a393d

	* tree-vect-stmts.c (vectorizable_assignment): Remove special
	allowance of VECTOR_BOOLEAN_TYPE_P conversions.
