I am breaking apart D99484 so the cause of build failures is easier to
understand.

This is the original patch in my GNUInstallDirs series, now last to merge as the final piece!
It arose as a new draft of D28234. I initially did the unorthodox thing of pushing to that when I wasn't the original author, but since I ended up
- Using `GNUInstallDirs`, rather than mimicking it, as the original author was hesitant to do but others requested.
- Converting all the packages, not just LLVM, effecting many more projects than LLVM itself.
I figured it was time to make a new revision.
I have used this patch series (and many back-ports) as the basis of https://github.com/NixOS/nixpkgs/pull/111487 for my distro (NixOS), which was merged last spring (2021). It looked like people were generally on board in D28234, but I make note of this here in case extra motivation is useful.
---
As pointed out in the original issue, a central tension is that LLVM already has some partial support for these sorts of things. Variables like `COMPILER_RT_INSTALL_PATH` have already been dealt with. Variables like `LLVM_LIBDIR_SUFFIX` however, will require further work, so that we may use `CMAKE_INSTALL_LIBDIR`.
These remaining items will be addressed in further patches. What is here is now rote and so we should get it out of the way before dealing more intricately with the remainder.

This builds on D116521 to add this functionality to Polly without more copy-pasted code.

Before this patch, the cmake disabled loadable modules when compiling
with Visual Studio. However, the reason for this is a limitation of the
Windows DLLs, thus this restriction should apply to any compiler for the
Windows platform, such as MinGW, Cygwin, icc, etc.

A build on `sparcv9-sun-solaris2.11` with `-DLLVM_ENABLE_PIC=Off` failed
linking `LLVMPolly.so`:
[2277/2297] Linking CXX shared module lib/LLVMPolly.so
FAILED: lib/LLVMPolly.so
[...]
ld: fatal: relocation error: R_SPARC_H44: file tools/polly/lib/CMakeFiles/obj.Polly.dir/Analysis/DependenceInfo.cpp.o: symbol .data._ZL16__gthread_active (section): invalid shared object relocation type: ABS44 code model unsupported
[...]
As on many other targets, one cannot link non-PIC objects into a shared
object on Solaris/sparcv9.
The following patch avoids this by not building the library without PIC.
It allowed the build to finish.

CMake generates the exports file wrongly if the CMAKE_BUILD_TYPE is
unset for multi-configuration generators.
The generated file lib/cmake/polly/PollyExports-all.cmake then contains:
set_target_properties(LLVMPolly PROPERTIES
IMPORTED_LOCATION_ my_build_dir/lib/LLVMPolly.so)
set_target_properties(Polly PROPERTIES
IMPORTED_LOCATION_ my_build_dir/lib/libPolly.a)
This patch conditionalizes the underscore.

Summary:
As of now, Polly uses llvm-config to set up LLVM dependencies in an out-of-tree build.
This is problematic for two reasons:
1) Right now, in-tree and out-of-tree builds in fact do different things. E.g., in an in-tree build, libPolly depends on a handful of LLVM libraries, while in an out-of-tree build it depends on all of them. This means that we often need to treat both paths seperately.
2) I'm specifically unhappy with the way libPolly is linked right now, because it just blindly links against all the LLVM libs. That doesn't make a lot of sense. For instance, one of these libs is LLVMTableGen, which contains a command line definition of a -o option. This means that I can not link an out-of-tree libPolly into a tool which might want to offer a -o option as well.
This patch (mostly) drop the use of llvm-config in favor of LLVMs exported cmake package. However, building Polly with unittests requires access to the gtest sources (in the LLVM source tree). If we're building against an LLVM installation, this source tree is unavailable and must specified. I'm using llvm-config to provide a default in this case.
