I tried but didn't crash.
```
#define vector __attribute__((vector_size(sizeof(double))))

vector double
foo1 (void)
{
  double v1 = 3.14159265359;
  double v2 = 1.383894;
  double vec_1_data[] = {v1};
  double vec_2_data[] = {v2};
  vector double vec_1 = {vec_1_data[0]};
  vector double vec_2 = {vec_2_data[0]};

  return vec_1*vec_2;
}
```

Before evrp on the working testcase:
```
  vec_1_data$0_3 = 3.14159265359000006156975359772332012653350830078125e+0;
  vec_2_data$0_4 = 1.3838939999999999574953335468308068811893463134765625e+0;
  _1 = vec_1_data$0_3;
  vec_1_9 = {_1};
  _2 = vec_2_data$0_4;
  vec_2_11 = {_2};
  [LP 1] _12 = vec_1_9 * vec_2_11;
```

But with the aarch64 intrinsics:
  vec_1_data$0_2 = 3.14159265359000006156975359772332012653350830078125e+0;
  vec_2_data$0_3 = 1.3838939999999999574953335468308068811893463134765625e+0;
  _10 = vec_1_data$0_2;
  _7 = {_10};
  _20 = vec_2_data$0_3;
  _21 = {_20};
  [LP 1] # .MEM_28 = VDEF <.MEM_4(D)>
  # USE = nonlocal escaped 
  # CLB = nonlocal escaped 
  _24 = __builtin_aarch64_fmulxdf (_10, _20);
```

aarch64_general_gimple_fold_builtin inside aarch64-builtins.cc which does the
folding and it looks correct.
`BUILTIN_GPF (BINOP, fmulx, 0, ALL)`

So it requires aarch64 intrinsics.
In GCC 12, the folding of fmulxdf or the multiply didn't happen during evrp
even.
