This patch adds support for them, such as types like Aarch64 __fp16, PowerPC __ibm128, and vector types thereof. This patch doesn't provide "full" support of AArch64 SVE, however, since for that we would need to support 'target' nodes (tracked in PR108080). Adding the new builtin types means that on Aarch64 we now have 217 global trees created on initialisation (up from 191), so this patch also slightly bumps the initial size of the fixed_trees allocation to 250.
