Owen Anderson 058088f219 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.

Daniel Dunbar 2edf3a4896 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. :)

Chris Lattner 2299d4b6d8 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.

Daniel Dunbar 84bc8c3058 Derive the right paths to use during testing instead of passing it in via make. 
Also, fix a few other details of the cmake test target and rename it to
'check'. CMake tests now work for the most part, but there are a handful of
failures left due to missing site.exp bits.
