dfa02ba434 cmp: unwind-label: relax conditions for carrying the value 
There is no need to carry the location value across the unwind when the
destination is not special, because then we may assign the destination before we
unwind the stack. That allows us to skip examining the unwind requirements.

c2ffcc5deb cmp: introduce a separate environment for functions 
There is an environment for the backend, and there is a separate environment for
each function.

def52d9657 cmp: pull emit-toplevel-form into emit-entry-fun 
Instead of mincing blocks form-by-form, we put them all in a single function
environment and make them share locals.

364deb0551 cmp: remove unused bindings 
EMIT-TOPLEVEL-FORM bound *compile-file-truename* and *compile-file-position* to
be immedietely rebound in T2EXPR (to the same value!).

*COMPILE-TO-LINKING-CALL* is not used anywhere.

b4da521398 cmp: set-loc: fix a braino (don't access special variable) 
set-loc saves the location to the destination, and while doing so it coerces the
former to the type of the latter. Our code used *destination* as the argument to
LOC-REPRESENTATION-TYPE, but DESTINATION and *DESTINATION* may not be the same.

f57fa4fab3 cmp: set-loc: accept explicit destination argument 
Most of the time when we've used SET-LOC we've rebound *DESTINATION* for that
particular operation. Instead of doing so right now the argument is explicit and
when we want to use the *DESTINATION* then we simply use it (literally 2 cases).

ef4ab04eda cmp: implement foreign data locations 
Instead of directly opencoding them in t3-defcallback we take a more organized
approach where we work with locations. This is part of larger refactor.

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.

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.
