Replace the ShouldRun() method with Apply() which will do the
transformation if it needs to be done, otherwise returns
'SkipTransform'.
This reduces a bunch of duplicated scanning between the old ShouldRun()
and Transform().
This change also adjusts code style to make the transforms more
consistent.

Previously Hashmap used to internally use a Hashset which held entries
of key-value pairs. This was cute, but meant that a Hashset held mutable
entries, which was a bag-of-bugs waiting to happen (change the entry to
hash as something different and you're now in an entirely broken state).
Pull the complex bits of Hashset out to HashmapBase, and have both
derive from that. I've opted for inheritance over composition here to
reduce the amount of structure chasing you'd have to do without
debugger pretty-printers.

When emitting the if true/false blocks we attempt to set the merge
target if the start block hasn't branched. This isn't right, as if the
block branched to other control flow, then that isn't the end of the
flow chain for that branch. We have to look at the current branch
target, and, if it exists, branch that to the if merge block.
