ArchSpec: fix unintentional promotion of unspecified unknowns to specified unknowns
* 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.
