The next step along the way to getting good error messages for bad archives. As mentioned in commit log for r276686 this next step is adding a new method in the ArchiveMemberHeader class to get the full name that does proper error checking, and can be use for error messages. To do this the name of ArchiveMemberHeader::getName() is changed to ArchiveMemberHeader::getRawName() to be consistent with Archive::Child::getRawName(). Then the “new” method is the addition of a new implementation of ArchiveMemberHeader::getName() which gets the full name and provides proper error checking. Which is mostly a rewrite of what was Archive::Child::getName() and cleaning up incorrect uses of llvm_unreachable() in the code which were actually just cases of errors in the input Archives. Then Archive::Child::getName() is changed to return Expected<> and use the new implementation of ArchiveMemberHeader::getName() . Also needed to change Archive::getMemoryBufferRef() with these changes to return Expected<> as well to propagate Errors up. As well as changing Archive::isThinMember() to return Expected<> . llvm-svn: 277177 2016-07-30 01:44:13 +08:00			`!<arch>`
