[PATCH, i386, AVX-512] Fix splitter for `not-xor' logic.

[Kirill Yukhin]

Hello Uroš,

This simple patch fixes mode (to iterator) in
splitter for `not-xor' logic.

Bootstrapped & reg-tested on trunk.

Is it ok for trunk?

Is it ok for gcc-5-branch? (if tested accordingly)

(I have no idea how to reference to define_split in
ChangeLog entry)

gcc/
        * gcc/config/i386/i386.md (define_split not/xor SWI1248x): Use
        iterator instead of fixed modes..

Thanks, K
