BLOCKER: LPython can't find dict key, but CPython can find it #2011

'a': 10, 'b': 11, 'c': 12, 'd': 13,
'A': 10, 'B': 11, 'C': 12, 'D': 13,
'e': 14, 'f': 15,
'E': 14, 'F': 15}

Here is a minimal reproducible example:
Gives:
If I remove any more keys from the dictionary, then it passes. It only happens in the LLVM backend, C works.

@czgdp1807 do you think you could please have a look at this? This looks like a bug in our dictionary implementation.
