Issue Description:

From Joe Groff in https://github.com/apple/swift/pull/5949

"I believe that the only place we use UUIDs in the compiler is to print "opened archetypes" in SIL in a way that lets them be reliably parsed back as unique types. We could probably use a better uniquing scheme in SIL printing now that we have better tracking of opened type uses in SIL, and kill the UUID dependency."

研究方向
The issue references a PR (#5949) where Joe Groff suggested a better uniquing scheme for opened archetypes in SIL printing. The contributor should investigate the current use of UUIDs in SIL, likely in the SIL printer. They should look at the comment in the PR and propose an alternative scheme, such as using an incremental counter or a hash that does not rely on libuuid.
