This patch unifies the comdat and non-comdat code paths. By doing this it add missing features to the comdat side and removes the fixed section assumptions from the non-comdat side. In ELF there is no one true section for "4 byte mergeable" constants. We are better off computing the required properties of the section and asking the context for it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@230411 91177308-0d34-0410-b5e6-96231b3b80d8
