[ELF] Convert Thunks to use InputSectionDescriptions
Thunks are now generated per InputSectionDescription instead of per OutputSection. This allows created ThunkSections to be inserted directly into InputSectionDescription. Changes in this patch: - Loop over InputSectionDescriptions to find relocations to Thunks - Generate a ThunkSection per InputSectionDescription - Remove synchronize() as we no longer need it - Move fabricateDefaultCommands() before createThunks Differential Revision: https://reviews.llvm.org/D33835 llvm-svn: 304887
