[flang][debug] Missing function/subroutine attribute {DW_AT_elemental, DW_AT_pure, DW_AT_recursive}

[jiel-nv]

Flang currently does not generate DWARF attribute DW_AT_elemental, DW_AT_pure and DW_AT_recursive for function/subroutine.

Need to emit metadata for DISubprogram field spFlags:, values are: DISPFlagElemental, DISPFlagPure, and DISPFlagRecursive. These procedure attributes info should be retrievable from the func operation.
