[PATCH] libctf: doc: add __float128 and SIMD vector classification to spec.

[Nick Alcock]

On 27 Jun 2025, Bruce McCulloch via Binutils stated:

> This patch adds two additional distinct types (__float128 and the SIMD
> vector type generated from the vector_size attribute) to the umbrella of
> two existing types (long double and array, respectively). These types
> were previously invalid, producing CTF_K_UNKNOWN in the case of
> __float128 or a float in the case of the SIMD vector. This patch will
> cleanly allow these types to be represented more accurately without
> breaking back-compat.
