Currently, it was delibrately impleneted to not handle this case, but as it has turnt out, we need this feature.
The concrete use case is
`System/Library/Frameworks/Cocoa.framework/Versions/A/Cocoa` reexports
/System/Library/Frameworks/AppKit.framework/Versions/C/AppKit , which then rexports
/System/Library/PrivateFrameworks/UIFoundation.framework/Versions/A/UIFoundation
The current implemention uses a global currentTopLevelTapi, which is not reset until it finishes loading the whole tree.
This is a problem because if the top-level is set to Cocoa, then when we get to UIFoundation, it will try to find UIFoundation in the current top level, which is Cocoa and will not find it.
The right thing should be:
- When loading a library from a TBD file, re-exports need to be looked up in the auxiliary documents within the same TBD.
- When loading from an actual dylib, no additional TBD documents need to be examined.
- In no case does a re-export mentioned in one TBD file need to be looked up in a document in an auxiliary document from a different TBD file

No longer rely on an external tool to build the llvm component layout.
Instead, leverage the existing `add_llvm_componentlibrary` cmake function and
introduce `add_llvm_component_group` to accurately describe component behavior.
These function store extra properties in the created targets. These properties
are processed once all components are defined to resolve library dependencies
and produce the header expected by llvm-config.

Summary:
This completes the needed glueing to support reading tbd files from nm.
This includes specifying which slice filtering with `--arch` and a new
option specifically for tbd files `--add-inlinedinfo` which will show
the reexported libraries that are appended in the tbd file.

Changing the underlying YAML support to allow returning a literal
string, rather than a StringRef, would probably be a bigger refactor so
I didn't do that.
Summary:
[llvm][TextAPI] adding inlining reexported libraries support
* this patch adds reader/writer support for MachO tbd files.
The usecase is to represent reexported libraries in top level library
that won't need to exist for linker indirection because all of the
needed content will be inlined in the same document.

This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.
This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.
This doesn't actually modify StringRef yet, I'll do that in a follow-up.
TAPI currently lacks a way to emit the macCatalyst platform. For TBD_V3
is does support zippered frameworks given that both macOS and
macCatalyst are part of the PlatformSet.

Summary:
Most libraries are defined in the lib/ directory but there are also a
few libraries defined in tools/ e.g. libLLVM, libLTO. I'm defining
"Component Libraries" as libraries defined in lib/ that may be included in
libLLVM.so. Explicitly marking the libraries in lib/ as component
libraries allows us to remove some fragile checks that attempt to
differentiate between lib/ libraries and tools/ libraires:
1. In tools/llvm-shlib, because
llvm_map_components_to_libnames(LIB_NAMES "all") returned a list of
all libraries defined in the whole project, there was custom code
needed to filter out libraries defined in tools/, none of which should
be included in libLLVM.so. This code assumed that any library
defined as static was from lib/ and everything else should be
excluded.
With this change, llvm_map_components_to_libnames(LIB_NAMES, "all")
only returns libraries that have been added to the LLVM_COMPONENT_LIBS
global cmake property, so this custom filtering logic can be removed.
Doing this also fixes the build with BUILD_SHARED_LIBS=ON
and LLVM_BUILD_LLVM_DYLIB=ON.
2. There was some code in llvm_add_library that assumed that
libraries defined in lib/ would not have LLVM_LINK_COMPONENTS or
ARG_LINK_COMPONENTS set. This is only true because libraries
defined lib lib/ use LLVMBuild.txt and don't set these values.
This code has been fixed now to check if the library has been
explicitly marked as a component library, which should now make it
easier to remove LLVMBuild at some point in the future.
I have tested this patch on Windows, MacOS and Linux with release builds
and the following combinations of CMake options:
- "" (No options)
- -DLLVM_BUILD_LLVM_DYLIB=ON
- -DLLVM_LINK_LLVM_DYLIB=ON
- -DBUILD_SHARED_LIBS=ON
- -DBUILD_SHARED_LIBS=ON -DLLVM_BUILD_LLVM_DYLIB=ON
- -DBUILD_SHARED_LIBS=ON -DLLVM_LINK_LLVM_DYLIB=ON

This is a patch for updating TextAPI/Macho to read in targets as opposed to arch/platform.
This is because in previous versions tbd files only supported a single platform but that is no longer the case,
so, now its tracked by unique triples.
