This patch mechanically replaces None with std::nullopt where the
compiler would warn if None were deprecated. The intent is to reduce
the amount of manual work required in migrating from Optional to
std::optional.
This is part of an effort to migrate from llvm::Optional to
std::optional:
https://discourse.llvm.org/t/deprecating-llvm-optional-x-hasvalue-getvalue-getvalueor/63716
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

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

SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior
runtime error: applying zero offset to null pointer
llvm/lib/Support/regengine.inc:151:18
The logical view is traversed and for each logical element a
series of match criterias are applied. One of those criterias
is to match its name or type name to a given pattern.
If the logical element does not have a type (for instance a
'namespace') do not try to use its type name, which is a
empty string as the 'matcher' function receives a null pointer.
