GHCi supports not-necessarily-lifted join points
Fixes #16509.
See Note [Not-necessarily-lifted join points] in ByteCodeGen,
which tells the full story.
This commit also adds some comments and cleans some code
in the byte-code generator, as I was exploring around trying
to understand it.
(This commit removes an old test -- this is really a GHCi problem,
not a pattern-synonym problem.)
test case: ghci/scripts/T16509
