Convert >= skipif to python script for clarity.
Remove "does not contain" skipif operator.

>= (aka does not contain) operator was added in #591, but now that general
python scripts can be used as skipif files it is no longer needed. >= is not
intuitive, so removing it now (before it is used throughout the test system)
is desirable.
Move perf graph sorting to genGraphs

Instead of sorting graphs online, sort them when we generate the graphs in
gengraphs.

The sorting functionality is still on for the javascript code. Turning it off
will come in a later commit.
Stop sorting graphs online. Already sorted in gengraphs now
Removing the TRIAGE file

A good idea, ultimately, it was unmaintainable.  Now using the
REGRESSIONS file for this purpose.
Add >= back in, after review feedback.

Refactor constant folding vs dead code elimination for CondStmt

During an effort to decouple dead-code elimination from the internal representation of  loops, I noticed
some entanglement between constant folding for IF statements with a literal boolean conditional and
dead code elimination.  This separates them and then pulls the dead-expression code from CondStmt 
to the core of the dead expression code.
