Peter Collingbourne 3f2921f5ec COFF: Do not create SectionChunks for discarded comdat sections. ... With this change, instead of creating a SectionChunk for each section in the object file, we only create them when we encounter a prevailing comdat section. Also change how symbol resolution occurs between comdat symbols. Now only the comdat leader participates in comdat resolution, and not any other external associated symbols. This is more in line with how COFF semantics are defined, and should allow for a more straightforward implementation of non-ANY comdat types. On my machine, this change reduces our runtime linking a release build of chrome_child.dll with /nopdb from 5.65s to 4.54s (median of 50 runs).
