* Determines if the provided source file may need to be processed by the linker, i.e. whether it
* potentially contains any declarations. If true is returned, then the source file should be
* processed by the linker as it may contain declarations that need to be fully compiled. If false
* is returned, parsing and processing of the source file can safely be skipped to improve
* performance.
*
* This function may return true even for source files that don't actually contain any declarations
* that need to be compiled.
*
* @param path the absolute path of the source file for which to determine whether linking may be
* needed.
* @param source the source file content as a string.
* @returns whether the source file may contain declarations that need to be linked.
