[llvm-branch-commits] GOFF: Only register sections within MCObjectStreamer::changeSection (PR #150183)

[Fangrui Song via llvm-branch-commits]

registerSection should only be called by
MCObjectStreamer::changeSection. This will be utilized by a pending
change to move initial fragment allocation from MCContext::createSection
to MCStreamer::changeSection, resolving some issues (Fragments should
only be created when using MCSteramer, not during
`MCContext::getELFSection` calls)
