Some data members are only part of a class definition in a Debug build,
e.g. `LVObject::ID`. If `debuginfologicalview` is used as a library,
`NDEBUG` cannot be used for this purpose, as this PP macro may have a
different definition in a downstream project, which in turn triggers an
ODR violation. Fix it by
- Making `LVObject::ID` an unconditional data member.
- Making `LVObject::dump()` non-virtual. Rationale: `virtual` is not
needed (and it calls `print()`, which is virtual anyway).

Fixes #139098.

llvm-debuginfo-analyzer is a command line tool that processes debug
info contained in a binary file and produces a debug information
format agnostic “Logical View”, which is a high-level semantic
representation of the debug info, independent of the low-level
format.

The code has been divided into the following patches:

1) Interval tree
2) Driver and documentation
3) Logical elements
4) Locations and ranges
5) Select elements
6) Warning and internal options
7) Compare elements
8) ELF Reader
9) CodeView Reader

This patch:

Compare elements
- Support for logical elements comparison. See '--compare' options.
  LVCompare
