[Lldb-commits] [lldb] [lldb][Instrumentation] GetPreferredAsanModule should be no-op on non-Darwin platforms (PR #132911)

[Michael Buch via lldb-commits]

https://github.com/Michael137 created https://github.com/llvm/llvm-project/pull/132911

The regex we use to find the compiler-rt library is already Darwin-specific, so no need to run this on non-Darwin platforms.
