[Bug target/19350] Compilation with -O1 -ftree-vectorize gives unrecognizable insn on x86.

I get a different error with today's compiler but that is because I am not 
compiling with --disable-
checking.
t.c:7: internal compiler error: in simplify_binary_operation, at 
simplify-rtx.c:2178

WTF:
(set (reg:V4SI 94)
        (vec_concat:V4SF (mem:V2SF (reg:SI 64 [ ivtmp.66 ]) [0 S8 A8])
            (vec_select:V2SF (reg:V4SI 94)
                (parallel [
                        (const_int 2 [0x2])
                        (const_int 3 [0x3])
                    ]))))

Which comes from the expansion of 
;; *(vect_p.22 + (vector int *) D.1440 * 16B - 16B) = M*ivtmp.66{misalignment: 
0}
