Alexey Samsonov 48cbda5850 DebugInfo: Introduce the notion of "form classes" 
Summary:
Use DWARF4 table of form classes to fetch attributes from DIE
in a more consistent way. This shouldn't change the functionality and
serves as a refactoring for upcoming change: DW_AT_high_pc has different
semantics depending on its form class.
