Log:
[ScopInfo] Use types instead of 'auto' and use more descriptive variable names [NFC]

LLVM's coding conventions suggest to use auto only in obvious cases. Hence,
we move this code to actually declare the types used. We also replace the
variable name 'SAI', with the name 'Array', as this improves readability.
