Teresa Johnson 6c475a7595 ThinLTO: add early "dead-stripping" on the Index ... Summary: Using the linker-supplied list of "preserved" symbols, we can compute the list of "dead" symbols, i.e. the one that are not reachable from a "preserved" symbol transitively on the reference graph. Right now we are using this information to mark these functions as non-eligible for import. The impact is two folds: - Reduction of compile time: we don't import these functions anywhere or import the function these symbols are calling. - The limited number of import/export leads to better internalization.
