Review the maximum size of a function body

[Ms2ger]

The maximum size of a function body, including locals declarations, is 7654321 bytes.

Let's use a round number.

This constant has some interesting history; see #607 (comment) . It used to be unenforced (in multiple browsers, due to separate bugs!), so it had to be raised to meet web reality.

What's the need for a round number? To me, this one seems as good as any; the important thing is that it be the same everywhere.

Agreed that this number is "cute", but since it's (nearly) arbitrary we can afford to be cute here. :-)

Closing, but feel free to reopen if there is more to discuss here.
