Use new MAP-RESTARTS in FIND-RESTART, COMPUTE-RESTARTS; fix FIND-RESTART
* Both FIND-RESTART and COMPUTE-RESTARTS traverse, filter and select
active restarts, potentially for a particular condition and
potentially calling restart test functions. This common behavior has
been factored into the new function MAP-RESTARTS.
* Remove *CONDITION-RESTARTS*; use new slot ASSOCIATED-CONDITIONS in
RESTART structure instead.
* As stated in bug 774410, when given a RESTART instance, FIND-RESTART
did not test whether the restart was still active and whether the
restart had been associated to a different condition in the
meantime. This behavior has been changed by calling MAP-RESTARTS which
checks activity and association to conditions (sadly, making
(find-restart RESTART-INSTANCE CONDITION-OBJECT)
a bit slower than before).
* INVOKE-RESTART is also affected by the changes for bug
774410. However, it does not respect restart test functions when
called with a RESTART instance (This is underspecified in CLHS and
other implementations behave in various ways. However, behaving
differently would make some restarts un-invokable).
* As suggested in bug 769615, (find-restart SYMBOL ...) now calls
MAP-RESTARTS instead of COMPUTE-RESTARTS, consing less and executing
faster in many cases.
* New (find-restart :recheck-conditions-and-tests :bug-774410) test from

Optimize CHAR-EQUAL on constant and base-char args.
The open-code transform for base-char arguments was never invoked, it
should have been defined on TWO-ARG-CHAR-EQUAL, not CHAR-EQUAL. And
enable it only for (> speed space).
Add a check for base-char into the TWO-ARG-CHAR-EQUAL function, and
invoke the optimized code, the same the transform uses.
Optimize (char-equal #\c x) by transforming it into a call to
(char-equal-constant x #\c #\C), which does
(or (char= #\c char) (char= #\C char)), or directly to that expression
with (> speed space).

Improve the test float.impure.lisp / (RANGE-REDUCTION PRECISE-PI).
The way the test calculated its expected values was flawed and worked
correctly only accidentally due to the specific test values used and
to allowing a relatively large margin of error.
This commit corrects these calculations, removes some test values and
adds others and tightens the error margin. I do not expect this to cause
the test's outcome on any platform to change.
The flaw was to reduce the arguments by taking the remainder of
truncating modulo 2 pi. This allows precise calculations only of the
sine and the tangent of values slightly above even multiples of pi, but
not for example for the sine of an argument near an odd multiple of pi.
Instead the reduction is now done by taking the remainder of rounding
to the nearest multiple of pi/2 so that all arguments near the zeroes
of both sine and cosine reduce to values near zero.
This change was prompted when the test unexpectedly failed with some
values from gcc bug 43490 which I tried when investigating lp #1137924.
