What this PR does / why we need it: this is basically an extension of #43642, but supports more general prerelease identifiers, per the spec at http://semver.org/#spec-item-9.
These regular expressions are still a bit more restrictive than the SemVer spec allows (we disallow hyphens, and we require the format
-foo.N
instead of arbitrary-foo.X.bar.Y.bazZ
), but this should support our needs without changing too much more logic or breaking other assumptions.Release note:
