Emit & read more compressed bytecode by not emitting a bytecodeblock for
each basic block in function. Instead, just emit a stream of instructions,
chopping up basic blocks based on when we find terminator instructions. This
saves a fairly substantial chunk of bytecode space. In stripped, sample
cases, for example, we get this reduction in size:
197.parser: 163036 -> 137180: 18.8% reduction
254.gap : 844936 -> 689392: 22.6%
255.vortex: 621724 -> 528444: 17.7%
...
Not bad for something this simple. :) Note that this doesn't require a new
bytecode version number at all, though version 1.1 should not need to support
the old format.
