Finally, a clean `bin/` tree. 😌
And as for the additional complexities in the Makefile, well, we're
about to get rid of that one anyway. 🚮

Running this on various PC-98 models confirms that unchecked blitting
(i.e., what you would intuitively consider to be the best method) is in
fact faster than checking either byte of a 16-pixel-wide sprite
beforehand, and has been throughout the PC-98's lifespan. For optimal
performance on the 286 and 386, we might want to use MOVS instead of
MOV, but even that difference is way too small to truly matter.
Also, nice to see turns out that our blitter outperforms a naive pure C
implementation by 2-4×, depending on the model. And master.lib is not
*that* much faster…

This Tupfile does in fact date back to January 2017, and I've been
using it myself ever since. Time to finally deliver it on master!

Two DOS utilities were made for this:
- gensize: generates TASM macro definitions with filesizes.
- copycat: similar to copy/b a+b+c d, except a+b+c is specified in a
separate file to avoid command line length limitations.
th02/zun.com is bit-perfect
th03/zun.com is almost there, with insignificant differences in
zunsp.com and res_yume.com.
