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.

When we enumerate loaded modules, we only track the module name and base address, which then has several problems on macOS. Dylibs and executables often have several architecture slices and not storing which architecture/UUID is actually loaded creates problems with symbolication: A file path + offset isn't enough to correctly symbolicate, since the offset can be valid in multiple slices. This is especially common for Haswell+ X86_64 machines, where x86_64h slices are preferred, but if one is not available, a regular x86_64 is loaded instead. But the same issue exists for i386 vs. x86_64 as well.
This patch adds tracking of arch and UUID for each LoadedModule. At this point, this information isn't used in reports, but this is the first step. The goal is to correctly identify which slice is loaded in symbolication, and also to output this information in reports so that we can tell which exact slices were loaded in post-mortem analysis.

Summary:
This removes the hard limit on the number of loaded modules (used to be
16K), and makes it easier to use LoadedModules w/o causing a memory
leak: ListOfModules owns the modules, and makes sure to properly clean
them in destructor.
Remove filtering functionality that is only needed in one place (LSan).
