The install-${name}-stripped targets don't strip when ${name} is being
symlinked, e.g. llvm-ar or llvm-objcopy. The problem is that
llvm_install_symlink passes install-${dest} as a dependency of
install-${name}, e.g. install-llvm-ar becomes a dependency of both
install-llvm-ranlib and install-llvm-ranlib-stripped. What this means is
that when installing a distribution that contains both llvm-ar and
llvm-ranlib is that first the stripped version of llvm-ar is installed
(by the install-llvm-ar-stripped target) and then it's overwritten by an
unstripped version of llvm-ar bnecause install-llvm-ranlib-stripped has
install-llvm-ranlib as a dependency as mentioned earlier. To avoid this
issue, rather than passing the install-${dest} as dependency, we
introduce a new argument to add_llvm_install_targets for symlink target
which expands it into an appropriate dependency, i.e. install-${dest}
for install-${name} target and install-${dest}-stripped for
install-${name}-stripped.

There's quite a lot of references to Polly in the LLVM CMake codebase. However
the registration pattern used by Polly could be useful to other external
projects: thanks to that mechanism it would be possible to develop LLVM
extension without touching the LLVM code base.
This patch has two effects:
1. Remove all code specific to Polly in the llvm/clang codebase, replaicing it
with a generic mechanism
2. Provide a generic mechanism to register compiler extensions.
A compiler extension is similar to a pass plugin, with the notable difference
that the compiler extension can be configured to be built dynamically (like
plugins) or statically (like regular passes).
As a result, people willing to add extra passes to clang/opt can do it using a
separate code repo, but still have their pass be linked in clang/opt as built-in
passes.

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

Summary:
The variable LLVM_NO_DEAD_STRIP is set in LLVM cmake files when building executables that might make use of plugins .The name of the variable does not convey the actual intended usage (i.e. for use with tools that have plugins), just what the eventual effect of setting in on some (i.e. not garbage collecting unused symbols).
This patch renames it to LLVM_SUPPORT_PLUGINS to convey the intended usage, which will allow subsequent patches to add behavior to support that in different ways without confusion about whether it will do on, for example, non-gnu platforms.

llvm-svn: 362248
Summary:
Clangd's framework is assembled by copying binaries from the lib and bin directories into a bundle shape. This results in an invalid bundle code signature because the signature only applies to the binaries not the resources.
This patch adds two new options to `llvm_codesign` to enable re-signing the library and XPC service as bundles.
The `BUNDLE_PATH` option allow specifying an explicit path to codesign, which enables signing bundles which aren't generated using CMake's `FRAMEWORK` or `BUNDLE` target properties.
The `FORCE` option allows re-signing binaries that have already been signed. This is required for how clangd exposes the clangd library and tools as both XPC and non-XPC services using the same binary.

A bunch of macros use the same variable name, and since CMake macros
don't get their own scope, the value persists across macro invocations,
and we can end up exporting targets which shouldn't be exported. Clear
the variable before each use to avoid this.
Converting these macros to functions would also help, since it would
avoid the variable leaking into its parent scope, and that's something I
plan to follow up with. It won't fully address the problem, however,
since functions still inherit variables from their parent scopes, so if
someone in the parent scope just happened to use the same variable name
we'd still have the same issue.

The old logic was using LLVM_EXTERNAL_LIT both as user-defined cache

(e.g. libcxx). It included a hack to make this work by assigning
the value back and forth but it was fragile and stopped working
in libcxx.
The new logic is simpler and more transparent. Default value is
