Base class describing the header of any kind of "unit." Some information is specific to certain unit types.

We separate this class out so we can parse the header before deciding what specific kind of unit to construct.

◆ applyIndexEntry()

◆ extract()

Parse a unit header from debug_info starting at offset_ptr.

Note that [SectionKind](classllvm%5F1%5F1SectionKind.html "SectionKind - This is a simple POD value that classifies the properties of a section.") is used as a hint to guess the unit type for DWARF formats prior to DWARFv5. In DWARFv5 the unit type is explicitly defined in the header and the hint is ignored.
