ansi-tests compiled

[Bruno H. <br...@cl...>]

Hi,

Paul Dietz' testsuite has even more checking power than we have already
used so far. I found a variable *compile-tests*. When set to T, it "simply"
causes all tests to be compiled before execution. The effects are that it
uncovered
   - 10 bugs in clisp's compiler (!), 7 of them dating back to 1992 at least
     (the other three being from 2001, 2004, 2005),
   - a bug in the most complex innards of CLOS, the method-combination
     code (!),
   - bugs in the IN-PACKAGE, TRACE, FORMATTER, WITH-OUTPUT-TO-STRING
     macros.

This is sufficiently important that I'm adding this mode of execution of
the tests to the "make check" target. (This doesn't mean a big slowdown,
since the compiled tests execution is more than twice as fast than the
interpreted tests execution. Probably because there are many tests that
just loop around 1000 times; this is so much faster when compiled that
it pays off the effort to compile all the tests.)
