Originally, gen_marshal_input_visit() (or gen_visitor_input_block()
before commit f1538019) was factored out to make it easy to do two
passes of a visit to each member of a (possibly-implicit) object,
without duplicating lots of code. But after recent changes, those
visits now occupy a single line of emitted code, and the helper
method has become a series of conditionals both before and after
the one important line, making it rather awkward to see at a glance
what gets emitted on the first (parsing) or second (deallocation)
pass. It's a lot easier to read the generator code if we just
inline both uses directly into gen_marshal(), without all the
conditionals.
Once we've done that, it's easy to notice that gen_marshal_vars()
is used only once, and inlining it too lets us consolidate some
mcgen() calls that used to be split across helpers.
gen_call() remains a single-use helper function, but it has
enough indentation and complexity that inlining it would hamper
legibility.
No change to generated output. The fact that the diffstat shows
a net reduction in lines is an argument in favor of this cleanup.
