Subject: Implement all operators specified for GLSL #if expressions (with
 tests).

The operator coverage here is quite complete. The one big thing
missing is that we are not yet doing macro expansion in #if
lines. This makes the whole support fairly useless, so we plan to fix
that shortcoming right away.
