Required Methods

Merge all modules into main_module and returning it

Performs fat LTO by merging all modules into a single one and returning it for further optimization.

Performs thin LTO by performing necessary global analysis and returning two lists, one of the modules that need optimization and another for modules that can simply be copied over from the incr. comp. cache.
