b05a1d116f Revert my previous patch to ABCD and fix things the right way. There are two problems addressed 
here:

1) We need to avoid processing sigma nodes as phi nodes for constraint generation.
2) We need to generate constraints for comparisons against constants properly.

This includes our first working ABCD test!

9feeeaf9ed Fix an issue where the ordering of blocks within a function could lead to different constraint 
graphs being produced.  The cause was that we were incorrectly marking sigma instructions as
processed after handling the sigma-specific constraints for them, potentially neglecting to
process them as normal instructions as well.

Unfortunately, the testcase that inspired this still doesn't work because of a bug in the solver,
which is next on the list to debug.

7e3089d3c6 Add a 'zkill' script, which is more-or-less a fancy (although not necessarily 
very robust) version of killall. Because I like making shiny new wheels out of
spare parts.

For use by buildbots when people insist on making cc1 infinite loop. :)

bf382b5f74 Teach an instcombine to not pull trunc instructions through PHI nodes 
when both the source and dest are illegal types, since it would cause
the phi to grow (for example, we shouldn't transform test14b's phi to
a phi on i320).  This fixes an infinite loop on i686 bootstrap with
phi slicing turned on, so turn it back on.

failures left due to missing site.exp bits.
