Fedora builds with LTO when building with clang upstream, which is an important difference from how we currently build their configuration. Having side by side builds of LTO and no LTO is valuable for quickly narrowing down issues caused or exposed by LTO. Add a Fedora + ThinLTO build to match the official configuration and catch any regressions with this configuration from LLVM. This is enabled for stable (6.8) and newer with LLVM 17 and newer to avoid adding too many builds to the matrix, which matches the versions of LLVM and the kernel that are in Fedora 40 and newer. This adds 90 builds per week. Closes: ClangBuiltLinux/linux#2009 Signed-off-by: Nathan Chancellor <nathan@kernel.org>
