Potential fix for https://github.com/llvm/llvm-project/issues/102939 and https://github.com/llvm/llvm-project/issues/102949. The issues occurs because the CodeExtractor component only collect inputs (to the parallel regions) that are defined in the same function in which the parallel regions is present. Howerver, this is problematic because if we are privatizing a global value (e.g. a `target` variable which is emitted as a global), then we miss finding that input and we do not privatize the variable. This commit attempts to fix the issue by adding a flag to the CodeExtractor so that we can collect global inputs.
