when a single vop has ~>= 50 operands.)

In the lifetime post-pass, added stuff to ensure that all results are 
marked as live before we start the ref-scan for the VOP.  This is necessary
to ensure the correct conflicts with dead results, especially in the
presence of results with :FROM specs.

properly inserted into the original TNs conflicts list.

Changes since 1.13: +25 -27 lines
Diff to previous 1.13
Changed alias and environment TN stuff to work with TNs that have no
references.  (We don't delete these TNs before lifetime analysis, since
because of alias TNs, TNs might appear to have no refs when they really
Also, changed debug-environment TN stuff to be more correct.  We set up
the conflicts before flow analysis, (just like for environment TNs) so that
environment TNs are considered always-live in blocks that they actually
die in when the block has successors.

Changes since 1.12: +1 -1 lines

Fixed typo in MERGE-ALIAS-CONFLICTS where I was using the initial value
rather than the loop variable in the body of the loop changing the
conflict TN for leftover conflicts.

Changes since 1.11: +343 -87 lines
Diff to previous 1.11
Changes to support :DEBUG-ENVIRONMENT and :ALIAS TNs, and new 
representation of conflicts for :ENVIRONMENT TNs.  Debug environment TNs
are used to hold things that don't absoultely have to be there
all the time, and that we would like to be able to target to/from.
These TNs are considered to be live in all blocks in the environment
that they aren't referenced in, and normal otherwise (more or less.)
Alias TNs are used to allow local call to directly assign the callee
variables in self-recursive calls without confusing environment

 Added support for :COMPONENT TNs.  Changed many TN-KIND tests to be
 (EQ ... :NORMAL), rather than being tests for not being :ENVIRONMENT,
 :CONSTANT, etc.

Oops...  We weren't dropping results from the live set, causing "saving" code
be emitted after each call (trashing the results).  Changed COMPUTE-SAVE-SET to
compute the correct bit-vector.  Changed :FORCE-TO-STACK code to use this
results with DO-LIVE-TNS, now that the list result isn't available.
