[llvm] don't set TracePCGuard as the default (PR #106464)

[Andrew Kelley via llvm-commits]

https://github.com/andrewrk created https://github.com/llvm/llvm-project/pull/106464

This allows library users to disable TracePCGuard along with those other options.

This "default" logic belongs in Clang, not LLVM.
