If a regular LTO module has a summary index, then instead of linking it into the combined regular LTO module right away, add it to the combined summary index and associate it with a special module that represents the combined regular LTO module. Any such modules are linked during LTO::run(), at which time we use the results of summary-based dead stripping to control whether to link prevailing symbols.
