Previously, when a prototype was parsed, this added a function declaration to the symbol table, but the prototype itself was not re-emitted during code generation. This meant that the final code might not be valid, since the absence of prototypes meant that the code might attempt to invoke a function before its declaration. Now, prototypes are stored in the ProgramElement list and re-emitted during code generation for GLSL/Metal/CPP. (SPIR-V doesn't name its functions at all.)
