Igor Kudrin c6ed1fcf24 [DebugInfo] Dump raw data in a case of decoding error of an expression. 
It looks like that was an initial intention, but some code paths in
`DWARFExpression::Operation::extract()` did not initialize `EndOffset`
properly.

Fangrui Song befbc99a7f Reland D79501 "[DebugInfo] Fix handling DW_OP_call_ref in DWARF64 units." 
With a fix to uninitialized EndOffset.

DW_OP_call_ref is the only operation that has an operand which depends
on the DWARF format. The patch fixes handling that operation in DWARF64
units.
