The basic idea here is reducing the number of functions whose
discriminating function and effective method cache are
precomputed; in particular, to reduce the number where users can
both legitimately define their own methods, and where a large
number of methods will be applicable to different classes.
The biggest culprit in both of those categories is the
PRINT-OBJECT generic function, which would recompute its entire
dispatch structure every time any method was added or removed.
So, turn off precomputation for names in the CL package; deal
with the bootstrap metacircles that that provokes; special-case
PRINT-OBJECT in COMPUTE-DISCRIMINATING-FUNCTION so that we can
always print certain critical pieces of infrastructure;
also, warn the user if they break our assumptions in
PRINT-OBJECT's specialization.
Fix one broken "how did it ever work" test.

1.0.17.31: more constant cleverness
* Make MAYBE-EMIT-MAKE-LOAD-FORM can dump _all_ references to
non-trivial named constants using the name (well, not FP constants
for SBCL itself.)
This means that after (DEFCONSTANT +FOO+ "FOO") all references to
+FOO+ are EQ, even in different files.
...some people are going to use this as an unportable performance
hack, and their code will break horribly sooner or later, but more
importantly we need to grovel less things, and more sharing means
less memory use and better cache behaviour.

:SORT-BY (:SAMPLES or :CUMULATIVE-SAMPLES) to REPORT, defaulting to
:DESCENDING and :SAMPLES as before. Makes eyeballing flat reports
easier, since often cumulative samples are the ones one should pay
attention to (esp. for :CPU and :TIME profiling.)
* Added support for profiling specific threads. New default is to
profile only the current thread when using WITH-PROFILING, and all
threads when using START-PROFILING -- :THREADS argument to both
WITH-PROFILING and START-PROFILING can be used to specify other
either a specific list of threads to profile, or :ALL to profile
all threads. (In the future we might want to add eg. :CHILDREN to
WITH-PROFILING, etc.)
** For :CPU profiling the signal handler simply filters out the
threads we are not profiling.
** For :ALLOC profiling, *ALLOC-SIGNAL* is now thread local, and
the profiler frobs the global *DEFAULT-ALLOC-SIGNAL* and local
*ALLOC-SIGNAL*s as needed. Before the runtime delivers the
allocation SIGPROF, it sets *ALLOC-SIGNAL* to T to prevent
problems with recursive allocation signals (seem better then
binding it in the handler, since we cannot really bind it quite
early enough no matter what we do.)

pthread_kill to notify threads.
