Correctly add unwinding info in manifestSp and makeFixupBlocks
In `manifestSp` the unwind info was before the relevant instruction, not
after. I added some notes to establish semantics. Also removes
redundant annotation in stg_catch_frame.
For `makeFixupBlocks` it looks like we were off by `wORD_SIZE dflags`.
I'm not sure why, but it lines up with `manifestSp`. In fact it lines
up so well so that I can consolidate the Sp unwind logic in
`maybeAddUnwind`. I detected the problems with `makeFixupBlocks` by
running T14779b after patching D4559.
Test Plan: added a new test
