History
John Stiles 26fdcbb38b Implement constant folding for (bool == bool) and (bool != bool). 
We already had support for &&, ||, ^^ but somehow the common cases of
== and != were not implemented in the constant-folder.

This CL also updates the test to return a green/red color on success or
failure, instead of assigning arbitrary numbers into sk_FragColor that
don't mean anything. The long-term plan is to signal success or failure
of each test by color code; we can display these colors as swatches in a
GM slide for testing purposes.
