[PATCH v2 1/2] rebase -i: pass struct replay_opts to parse_insn_line()

["Phillip Wood via GitGitGadget" <gitgitgadget@gmail.com>]

From: Phillip Wood <phillip.wood@dunelm.org.uk>

This new parameter will be used in the next commit. As adding the
parameter requires quite a few changes to plumb it through the call
chain these are separated into their own commit to avoid cluttering up
the next commit with incidental changes.
