Merge copies of converting an XID to a FullTransactionId.

Assume twophase.c is the performance-sensitive caller, and preserve its
choice of unlikely() branch hint. Add some retrospective rationale for
that choice. Back-patch to v17, for the next commit to use it.

Reviewed (in earlier versions) by Michael Paquier.
