Protected Attributes
DIE *	OutDIE = nullptr
	Output DIE.
CompileUnit &	InUnit
	Input compilation unit.
CompileUnit::OutputUnitVariantPtr	OutUnit
	Output unit(either "plain" compilation unit, either artificial type unit).
SectionDescriptor &	DebugInfoOutputSection
	.debug_info section descriptor.
const DWARFDebugInfoEntry *	InputDieEntry = nullptr
	Input DIE entry.
uint32_t	InputDIEIdx = 0
	Input DIE index.
DIEGenerator &	Generator
	Output DIE generator.
std::optional< int64_t >	FuncAddressAdjustment
	Relocation adjustment for the function address ranges.
std::optional< int64_t >	VarAddressAdjustment
	Relocation adjustment for the variable locations.
bool	HasLocationExpressionAddress = false
	Indicates whether InputDieEntry has an location attribute containg address expression.
unsigned	AttrOutOffset = 0
	Output offset after all attributes.
OffsetsPtrVector	PatchesOffsets
	Patches for the cloned attributes.
bool	Use_DW_FORM_strp = false
	This flag forces using DW_FORM_strp for string attributes.

This class creates clones of input DIE attributes.

It enumerates attributes of input DIE, creates clone for each attribute, adds cloned attribute to the output DIE.
