Close https://github.com/llvm/llvm-project/issues/60544. The root cause for the issue is that when we compile a module unit, the file manager (and proprocessor and source manager) are owned by AST instead of the compilaton instance. So the file manager may be invalid when we want to create a time-report file for -ftime-trace when we are compiling a module unit. This patch tries to recreate the file manager for -ftime-trace if we find the file manager is not valid.
