As mentioned in #108633, we don't respect the lower bound of the assumed shape arrays if those were specified. It happens in both cases: 1. When caller has non-default lower bound and callee has default 2. When callee has non-default lower bound and caller has default This PR tries to fix this issue by improving our generation of lower bound attribute on DICompositeTypeAttr. If we see a lower bound in the declaration, we respect that. Note that same function is also used for allocatable/pointer variables. We make sure that we get the lower bound from descriptor in those cases. Please note that DWARF assumes a lower bound of 1 so in many cases we don't need to generate the lower bound. Fixes #108633.
