* ArchSpec::MergeFrom() would erroneously promote an unspecified unknown to a specified unknown when both the ArchSpec and the merged in ArchSpec were both unspecified unknowns. This no longer happens, which fixes issues with global module cache lookup in some situations. * Added ArchSpec::DumpTriple(Stream&) that now properly prints unspecified unknowns as '*' and specified unknows as 'unknown'. This makes it trivial to tell the difference between the two. Converted printing code over ot using DumpTriple() rather than building from scratch. * Fixed up a couple places that were not guaranteeing that an unspecified unknown was recorded as such. llvm-svn: 250253
