[PATCH] D55891: [compiler-rt] [xray] [tests] Detect and handle missing LLVMTestingSupport gracefully

[Stefan Gränitz via Phabricator via cfe-commits]

sgraenitz added a comment.

In case compiler-rt abandons `llvm-config` in favor of `find_package(LLVM)` one day, we could drop the `COMPILER_RT_HAS_LLVMTESTINGSUPPORT` logic here and use imported target properties instead. It seems a cleaner solution to me and avoids issues like D57521 <https://reviews.llvm.org/D57521>.
