Isn't this only true for GCC code that operates above the GENERIC form level?

Not sure what you're saying here.

The ‘GC’ refers to garbage collector, not GCC.

It is true that you can write a compiler frontend targeting a generic backend (like GCC), and take advantage of existing optimizations. Truffle's somewhat unique value prop is that you can write a basic interpreter (not compiler) and get performance approaching that of a top-end JIT.
