Unused __builtin_ia32_* builtins

[Jakub Jelinek <jakub at redhat dot com>]

Hi!

for i in `grep __builtin_ia32 config/i386/i386-builtin.def | sed 's/^.*__builtin_ia32_/__builtin_ia32_/;s/".*$//' | sort -u`; do grep -q -w $i config/i386/*.h || echo $i; done

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?

E.g. __builtin_ia32_add{pd,ps}{,256} were used in intrinsic headers in <=
4.9.x and unused afterwards.  __builtin_ia32_ceilpd I can't find in any
header of any version.  Perhaps just start with the builtins that were used
in <= 4.9.x headers and aren't anymore (that is the first list until empty
line, rest are builtins not appearing in 4.9 intrinsic headers either).
