[DebugInfo] Add DebugTypeArrayDynamic translation (#1871)
This instruction describes a dynamic array, mostly for Fortran 90. Unlike DebugTypeArray it has Data Location, Associated, Allocated and Rank parameters. If the appropriate metadata parameters appear in LLVM IR in DW_TAG_array_type metadata, then such debug type becomes treated as dynamic array by the translator (of course if the appropriate extended instruction set is enabled). Spec: KhronosGroup/SPIRV-Registry#186 Signed-off-by: Sidorov, Dmitry <dmitry.sidorov@intel.com>
