Optimize special variable binding on sb-thread.

Remove a level of indirection when unbinding special bindings, instead
of saving a symbol on the binding stack, and then accessing its
tls-index to unbind it, save the tls-index directly, saving one memory

Fix loading specialized vectors from fasls.

Previously vectors were dumped and loaded based on the hand crafted
typecase forms, which was quite fragile.
After the dumping part was rewritten to consult
sb-vm:*specialized-array-element-type-properties*, the loading part
broke down.
Change the way it's done altogether, simplifying things significantly.
Instead of having separate FOPs for signed and unsigned vectors,
writing bit size of elements, just dump the widetag and use just a
single FOP, fop-spec-vector. Floating point dumping routines now use
fop-spec-vector too.

Don't store the address in a linkage-info structure, only the linkage-info-address

Restore building of +sb-unicode with -sb-unicode.

Some host definitions slipped in during cross-compilation.
char-code-limit => sb!xc:char-code-limit.
**character-primary-compositions** was initialized at xc-time, move it to cold init.

Thanks to Christophe Rhodes for the latter.

It should therefore not trigger AVER failures if the user gets the
order of arguments wrong, but report the problem sanely. The fix
in this commit is only semi-sane; it would be nice to report an
expected-type of SB-MOP:FUNCALLABLE-STANDARD-OBJECT rather than
SB-KERNEL:FUNCALLABLE-INSTANCE, but there are slightly tricky
bootstrap issues to sort out to get that to work.

minor optimization to restart-case

The generated non-local transfer functions go to a tag which will
always be in scope whenever the restart can be invoked, so wrap the
GO in a scary (safety 0) optimization declaration. This fixes
lp#1023721 (but not the issue raised in comment #1, which would be
solved naturally if lp#383078 is addressed).

Include a test which deliberately breaks the normal dynamic-extent
lifetime for restarts; restarts generated by RESTART-CASE and friends
in fact have indefinite extent, even though once they're out of the
dynamic-extent of their creating/binding operator you can't really do
anything with them (INVOKE-RESTART signals a control-error if the
restart given is not active, and there's no way to reactivate a
restart). However, the temptation to make the restart function
have dynamic-extent allocation must be resisted, because of the
indefinite lifetime of the restart object itself.

Fix CHAR-EQUAL on base-chars on non-sb-unicode.

BASE-CHAR-P, called by TWO-ARG-CHAR-EQUAL, isn't properly implemented
on non-sb-unicode, the transform by which it gets transformed into
(typep x 'base-char) is disabled, causing an infinite loop.
Since testing for base-char-p is usually redundant on #-sb-unicode,
don't define it there at all. This will catch inadvertent uses.

rename SB-SIMPLE-STREAMS utility function

At least, I think it was simply intended to be a utility function,
but the FILE-NAMESTRING name is unfortunate, as that's a CL function,
and (for other reasons) SB-SIMPLE-STREAMS claims to implement CL in
the package lock sense, so this was not noticed at the time.

This fixes lp#884603; I am unconvinced that the namestring logic is
actually correct (keeping the distinction between NAMESTRING and
NATIVE-NAMESTRING clear) but I'll wait for an actual user to complain
about that before thinking too hard.
