LOG:     [flang]Add examples in documentation/BijectiveInternalNameUniquing.md

    Summary:
    I thought it would be simpler to understand on how the unique names would
    look like when an example is present. So I added some examples.

    I found 2 such places to add examples
    -Common blocks
    -Module scope global data
