[PATCH] D33835: [LLD][ELF] Convert Thunks to use InputSectionDescriptions

[Peter Smith via Phabricator via llvm-commits]

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

This is patch 3/3 of the conversion of ThunkCreator to insert Thunks into InputSectionDescription. The patch is dependent on the previous 2 refactoring patches on ThunkCreator https://reviews.llvm.org/D33832, https://reviews.llvm.org/D33834. In addition it is also dependent on  https://reviews.llvm.org/D33772 SHF_LINK_ORDER sections using InputSectionDescriptions as we need that to be able to remove synchronize().
