This patch adds support for DWARF attribute DW_AT_rank. Summary: Fortran assumed rank arrays have dynamic rank. DWARF attribute DW_AT_rank is needed to support that. Testing: unit test cases added (hand-written) check llvm check debug-info Reviewed By: aprantl Differential Revision: https://reviews.llvm.org/D89141
