opt: don't clear streams of bytes on the stack
...
All over the Mu code I reflexively initialize all variables just to keep
unsafe SubX easy to debug. However I don't really need to do this for safe
Mu code, since the type- and memory-safety already ensures we can't read
from streams beyond what we've written to them. For now I'll continue mostly
with the same approach, but with one exception for streams of bytes.
Mu programs often emit traces, and in doing so they often use temporary
streams of bytes that can get quite long. I'm hoping avoiding initializing
KBs of data all over the place will measurably speed up the Mu shell.

snapshot: stupid debugging session
...
I spent a while building a little keyboard scancode printer:
$ ./translate ex1.mu && qemu-system-i386 disk.img
..and wondering why up-arrow was 0x48 in hex but 724 in decimal. I ended
up paranoidly poking at a bunch of crap (though there _is_ a cool chromatography-based
debugging technique in 126write-int-decimal.subx) before I realized:
- 724 just has one extra digit over the correct answer
- the 0xe0 scan code is a 3-digit number in decimal -- and the final digit is '4'
There's nothing actually wrong.
