backport: re PR target/57896 (ICE in expand_expr_real_2) 

Backport from mainline
	2014-02-21  Jakub Jelinek  <jakub@redhat.com>

	* config/i386/i386.c (ix86_expand_vec_perm): Use V8SImode
	mode for mask of V8SFmode permutation.

	Backport from 4.8 branch
	2014-02-20  Jakub Jelinek  <jakub@redhat.com>

	PR target/57896
	* config/i386/i386.c (expand_vec_perm_interleave2): Don't call
	gen_reg_rtx if d->testing_p.
	(expand_vec_perm_pshufb2, expand_vec_perm_even_odd_1,
	expand_vec_perm_broadcast_1): Return early if d->testing_p and
	we will certainly return true.
