GCC with version 10 onward does not treat intrinsic type(int8x16_t) and __vector_type(vector_size(16) int8_t) are the same which lead to is_vector_type<Tp> failure. Meanwhile, clang use __attribute__((neon_vector_type)) is not same type with __attribute__((__vector_size__())) Above all, is_vector_type should be judged by logical "or" with the same<Tp, __vector_type> and same<Tp,__intrinsic_type> ChangeLog: * experimental/bits/simd.h: refactor the is_vector_type taking vector_type and intrinsic_type as independent types

GCC with version 10 onward does not treat intrinsic type(int8x16_t)
and __vector_type(vector_size(16) int8_t) are the same which lead
to is_vector_type failure.
Meanwhile, clang use attribute((neon_vector_type)) is not same
type with attribute((vector_size()))
Above all, is_vector_type should be judged by logical "or"
with the same<Tp, __vector_type> and same<Tp,__intrinsic_type>
