As part of the WebAssembly support work review
https://github.com/llvm/llvm-project/pull/82588
It was decided to rename:
Files: LVElfReader.cpp[h] -> LVDWARFReader.cpp[h]
ELFReaderTest.cpp -> DWARFReaderTest.cpp
Class: LVELFReader -> LVDWARFReader
The name LVDWARFReader would match the another reader LVCodeViewReader
as they will reflect the type of
debug information format that they are parsing.
Add support for the WebAssembly binary format and be able to generate
logical views.

The README.txt includes information about how to build the test cases.
If a category has no options associated with it, the `--help-hidden`
command still shows that category with the annotation "This option
category has no options", and this is how it was implemented from the
beginning when the categories were introduced, see commit 0537a98878. A
feature to hide unrelated options was added later, in
https://reviews.llvm.org/D7100. Now, if a tool needs to hide unrelated
options that are associated with categories, leaving some of them empty,
those categories will still be visible on the `--help-hidden` output,
even if they have no use for the tool; see the changes in
`llvm/test/tools/llvm-debuginfo-analyzer/cmdline.test` for an example.
The patch ensures that only categories with options are shown on both
main and hidden help output.
Relax the assumption that at most one Reference-or-Type-like attribute is
present on a DWARF DIE.
Add support for at most one Type attribute (i.e. DW_AT_import xor
DW_AT_type) and separately at most one Reference attribute (i.e.
DW_AT_specification xor DW_AT_abstract_origin xor ...).
Update comment describing old assumption and tag it as a "FIXME" to
reflect the fact that this is perhaps still not general enough.
Add a test based on the case which led me to encounter the bug in the
wild.

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

Fix mismatch between `%d`/`%x` format strings and `uint64_t` type.
This fixes incorrect printing of "Scope Sizes" on 32-bit platforms
where this leads to `llvm::print()` misreading vararg.
Fixes#58758

The sanitizer reported memory leak issues; the command line
used in the test case is:
llvm-debuginfo-analyzer --attribute=level
--print=instructions
pr-incorrect-instructions-dwarf-clang.o
When dealing with logical instruction lines associated with
an artificial logical scope, skip the process of finding
their enclosing scope. Just add them to the scope.
Create logical debug lines only if the command line specifies:
--print=lines or --print=elements or --print=all
