shows many builtins not used in any of the intrinsic headers.
I believe for the __builtin_ia32_* builtins we only support the intrinsics
and not the builtins directly. Can we remove some of these (not necessarily
all of them), after checking when and why they were added and if they were
added for the intrinsic headers which now e.g. uses generic vector arith
instead?
When I removed their use in the intrinsic headers, I tried to remove them,
but Ada people asked us to keep them
