Delete unnecessary generality in loadFile. loadFile could load mulitple files just because yaml has a feature for putting multiple documents in one file. Designing a linker around what yaml can do seems like a bad idea to me. This patch changes it to read a single file. There are further improvements to be done to the api and they will follow shortly. llvm-svn: 235724

[core] support .gnu.linkonce sections .gnu.linkonce sections are similar to section groups. They were supported before section groups existed and provided a way to resolve COMDAT sections using a different design. There are few implementations that use .gnu.linkonce sections to store simple floating point constants which doesnot require complex section group support but need a way to store only one copy of the floating point constant in a binary. .gnu.linkonce based symbol resolution achieves that.

[Core] Fix handling of Section Groups. There is code(added by me) in the YAMLReader which isn't correct when it handles references for section groups. The test case was also checking for wrong outputs. This fixes the bug and the testcase so that they check for proper outputs. llvm-svn: 230190
