Summary:
Before this diff:
```
// Summary of const global
// { global -> v }
n$0 =* global
// n$0 -> {global}
x *= n$0
// x -> {global}
```
However, this is incorrect because we expect `x` have `v` instead of the abstract location of `global`.
To fix the issue, this diff lookups the initializer summary when `global` is evaluated as RHS of load statement.
After this diff:
```
// Summary of const global
// { global -> v }
n$0 =* global
// n$0 -> v
x *= n$0
// x -> v
```

Summary: This diff fixes the array access checking function for nested global arrays. We had assumed that RHS of `store` statement in SIL does not include array access expression, but that is not true: for global arrays, SIL can have statements like `*LHS = GlobalArray[n][m]`.

This diff gets global constant array values from their initializers. The `find_global_array` function is
added to memory domain, which finds values of global array locations during the ondemand value
generation.
