Testcase (compile with -O2 -mavx):
--cut here--
typedef float V __attribute__ ((vector_size (32)));
typedef unsigned int VI __attribute__ ((vector_size (32)));
extern V a, b, c, d;
void test_9 (void)

VI mask = { 13, 11, 10, 15, 8, 5, 14, 8 };
d = __builtin_shuffle (a, b, mask);
}

Confirm.
Caused by my changes:

* config/i386/i386.c (expand_vec_perm_pblendv): New.
* config/i386/i386.c (ix86_expand_vec_perm_const_1): Use
expand_vec_perm_pblendv.

138bc75d-0d04-0410-961f-82ee72b054a4
For 32 bytes AVX there are 1 operand permutations requiring more than 1
instruction.
So we should restrict the case here.
I'll make a patch for this.
