[Bug rtl-optimization/34529] New: Wrong code with altivec and offsets

[pinskia at gcc dot gnu dot org]

Testcase:
vector float b[560560];
vector float c[560560];
void f(void);
vector float Mult(vector float a)
{
  b[560560/16] = a;
  asm
("":::"memory","0","3","4","5","6","7","8","9","10","11","12","14","15","16","17","18","19","20","21","22","23","24","25","26","27","28","29");
  b[560560/16] = a;
}

---- CUT ----
We get:
        lis 9,0x8
        ori 9,9,36272
        add 9,9,9
        stvx 0,0,9

Which is obviously wrong.
