[SYCL][Test] Update ap_fixed test after IR change

It is named var instead of number now, update the regex.

After
llvm/llvm-project@9ad72df
From:

```
  %0 = load i13, ptr addrspace(4) %a.addr.ascast, align 2, !tbaa !7
  %call = call spir_func signext i5 @_Z22__spirv_FixedSqrtINTELILi13ELi5EEDBT0__DBT__biiii(i13 signext %0, i1 zeroext false, i32 2, i32 2, i32 0, i32 0) #2
```

to:

```
  %0 = load i16, ptr addrspace(4) %a.addr.ascast, align 2, !tbaa !7
  %loadedv = trunc i16 %0 to i13
  %call = call spir_func signext i5 @_Z22__spirv_FixedSqrtINTELILi13ELi5EEDBT0__DBT__biiii(i13 signext %loadedv, i1 zeroext false, i32 2, i32 2, i32 0, i32 0) #2

```
