This cl enables true integer support in glsl shaders.
It still uses floating point registers to store all
registers, regardless of the type, so integer and
unsigned integer variables are simply reinterpreted
as integers or unsigned integers and used as such by
the appropriate instructions.

Bit shifts compilation was failing when the types were a mismatch,
but shifting a uint by an int (or vice versa) is allowed, so types
may not match, and it's fine, as long as both are integer types.

Very few operations were missing in Nucleus for integer types

These were simply un-commented out as they were already there,
just commented out.
