Prototype helper functions from FP files before use.

GLSL requires that functions are declared before first use. In most
cases, we avoid the requirement for explicit prototypes by this by
strategically ordering our functions within the emitted code, but an FP
file might reference its helper functions in any order or have helper
functions that cross-invoke each other, so prototypes should be emitted.
