Kinds of declarator that cannot contain a qualified function type.

HandleNeonVectorTypeAttr - The "neon_vector_type" and "neon_polyvector_type" attributes are used to create vector types that are mangled according to ARM's ABI.
Otherwise, these types are identical to those created with the "vector_size" attribute. Unlike "vector_size" the argument to these Neon attributes is the number of vector elements, not the vector size in bytes. The vector width and element type must match one of the standard Neon vector types.

HandleVectorSizeAttribute - this attribute is only applicable to integral and float scalars, although arrays, pointers, and function return values are allowed in conjunction with this construct.
Aggregates with this attribute are invalid, even if they are of the same size as a corresponding scalar. The raw attribute should contain precisely 1 argument, the vector size for the variable, measured in bytes. If curType and rawAttr are well formed, this routine will return a new vector type.

Because declarator chunks are stored in outer-to-inner order, testing every chunk before endIndex
is testing all chunks that embed the current chunk as part of their type.
