8-byte modes should be processed only for TARGET_MMX_WITH_SSE.
gcc/ChangeLog:
* config/i386/i386-expand.cc (expand_vec_perm_pblendv):
Handle 8-byte modes only with TARGET_MMX_WITH_SSE.
(expand_vec_perm_2perm_pblendv): Ditto.
Bootstrapped and regression tested on x86_64-linux-gnu {,-m32}.
Pushed to master.
Uros.
