compiler: improve and & or.
* share/txr/stdlib/compiler.tl (compiler comp-and-or): Handle
the trivial zero and one argument cases separately. In
particular, the one-argument case results in better code
because it eliminates a temporary register. We don't have
to test for the zero-arg case any more in the general case,
so it is simplified in a few cases.
