938a757220 cmp: merge operators with-exit-label and with-optional-exit-label 
Their core difference was that the latter coudl reuse the destination. We make
the exit argument explicit and optional in with-exit-label.

abd109c982 cmp: further rewrite the exit manager for clearity 
This commit makes the exit type explicit and removes a need to test the result
of UNWIND-COND.

c03d856556 cmp: rewrite the exit manager for clearity 
This commit rewrites UNWIND-EXIT to explicitly handle conditional jumps. We
remove misleading SET-JUMP-{TRUE,FALSE} and implement them locally.

f0634e3301 cmp: remove invalid optimization from unwind-exit 
The optimization assumed, that we don't need to unwind stacks when there are no
bds nor stack frame changes. That leads to a corrupted IHS environment among
other things.

38e45ad026 cmp: exit manager has now two main ops UNWIND-EXIT and UNWIND-JUMP 
unwind-exit assigns the destination and jumps to the target
unwind-jump ignores the destination and jumps to the target

4d412cc6f9 cmp: LABEL captures the current *UNWIND-PROTECT* as LABEL-DENV 
Thanks to this change we may get rid of explicit TAG-UNWIND-PROTECT slot in
favor of relying on the tag label. Also rename TAG-LABEL to TAG-JUMP to
emphasize similarity to BLK-EXIT.

0041e7d8da cmp: use correctly with-exit-label 
Previusly we've duplicated some code with regard to this macro, most notably
we've bound *exit* separately to label instead of passing it as a first arg.

e54b944e7a cmp: don't refer to module functions as local-funs 
It is a historical baggage from before FSET. Functions stored in *local-funs*
are both local and global, so sipmly rename it to *functions*.

b7ad56faff cmp: cleanup: remove a misleading comment for VAR-LOC 
In the past VAR-LOC in the first pass could have a value 'CLB to indicate, that
it can't be allocated on the C stack. But somewhere along the way the structure
gained a separate slot REF-CLB that indicates that and VAR-LOC in the 1st pass
is /always/ OBJECT.

Update comments to reflect that fact and remove no-op assignments.

d308c5cdfb cmp: object-type: do not depend on an exact type name 
Previously object-type first called (TYPE-OF THING) and then matched it with
exact type names. This fails when we have a more precise type, i.e

   (type-of 3)                 -> (integer 3 3)
   (eq 'fixnum '(integer 3 3)) -> nil
   =>
   (object-type 3)             -> T

and that left us with subpar optimizations down the road.

1b8d1041dd cmp: optimize-cxx-data: reorder optimizations 
Previously we've tried first to add-static-constnat, although that led to a
situation where we've created static constant even if we had that value in the
core. Right now a static constant is the last thing to try when we attempt to
optimize the object. The order is quite arbitrary - the comment before the
function explains that we could avoid coercion with some additional work.

e8f3609078 cmpc: split CALL-UNKNOWN-GLOBAL-LOC to -LOC and -FUN 
Both variants have distinct and mutually exclusive (based on the code) usages.
Moreover, when dealing with a function name, always use FDEFINITION location.

This is a speculation, but only basic cases were handled with FDEFINITION
because WT-FDEFINITION could only handle symbols in CL package and otherwise a
slower method was used. WT-FDEFINITION can handle now all valid function names
including (SETF FOO) and function names not contained in core packages.
