Thus far the compiler has used the "staticUse" flag to mark variables
that should have rather been marked "active", meaning that the code
may actually execute in a way that accesses the variable. There's a
clear definition for this use of the term "active" in the GLES 3.0.5
spec, section 2.12.6, and in GLES 3.1 section 7.3.1.

Having separate fields for recording static use and "activeness" of a
variable is the first step to fixing this.

According to the spec, usually only active resources should be
considered when checking use against max limits. Also, only active
uniforms get assigned a location. libANGLE code now correctly checks
the active flag rather than the static use flag in these cases.

The static use field still mirrors the active field for now, since
some code in Chromium also needs to be fixed to use the active field
correctly before the two can diverge.

After Chromium is fixed, we can fix ANGLE so that static use
information is recorded earlier during compilation and will accurately
reflect whether variables are statically used. Currently the compiler
only records variables once some static use may already have been
pruned from the AST.

a series of switch statements using the hash value of the look-up

This increases compiler init performance significantly, as well as
increasing compiler perf test scores around 1-2%. Binary size is
