dcff3961c2 [DWARF] Return Error from DWARFDebugArangeSet::extract().
This helps to detect and report parsing errors better.
The patch follows the ideas of LLDB's patches D59370 and D59381.

It adds tests for valid and some invalid cases. More checks and
tests to come. Note that the patch fixes validation of the Length
field because the value does not include the field itself.

The existing users are updated to show the error messages.

5e017c12d2 [DWARF] Allow empty address range tables.
Empty address range tables are allowed by the DWARF standard;
Moreover, generating them is recommended as a best practice, see

2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

82af9438d0 Move DebugInfo to DebugInfo/DWARF.
In preparation for adding PDB support to LLVM, this moves the
DWARF parsing code to its own subdirectory under DebugInfo, and
renames LLVMDebugInfo to LLVMDebugInfoDWARF.

This is purely a mechanical / build system change.
