[llvm] [ThinLTO] Don't always print ModulesToCompile debugging information (PR #106769)

[Nick Sarnie via llvm-commits]

https://github.com/sarnex created https://github.com/llvm/llvm-project/pull/106769

Nothing went wrong in this case, we just succesfully matched a module by identifier. No need to print to std::error like we would for something that should be user-visible.

Subject: [PATCH] [ThinLTO] Don't always print ModulesToCompile debugging
 information

Nothing went wrong in this case, we just succesfully matched a module by
identifier. No need to print to std::error like we would for something
that should be user-visible.
