[flang-commits] [flang] [flang][debug] Correct pointer size. (PR #120781)

[Abid Qadeer via flang-commits]

https://github.com/abidh created https://github.com/llvm/llvm-project/pull/120781

We were passing size in bytes for the sizeInBits field in DIDerivedTypeAttr with DW_TAG_pointer_type. Although this field is un-used in this case but better to be accurate.
