[flang-commits] [flang] [Flang]: Use actual endianness for Integer<80> (PR #103928)

[Daniel Chen via flang-commits]

https://github.com/DanielCChen created https://github.com/llvm/llvm-project/pull/103928

This PR is to use the actual endianness of the platform when instantiate Integer<80> so that AIX (big-endian) will not get confused.
