TinyCC/tcc vs zig cc compile-times/etc.

[shirleyquirk]

I couldn't get zig to magically speed up my compile times, either; I've been 
using [zapcc](https://github.com/yrnkrn/zapcc) for some time now, which is 
noticeably quicker than gcc. I tried it on your suggest.nim and got: 
    
    
    gcc: 4.5s
    zapcc: 3.4s
    tcc: 1.7s
    
    
    Run

of that, the Nim compilation is like 1.7s. tcc is just stupidly fast.

on `bench.c` i get: 
    
    
    gcc: 0.03
    tcc: 0.004
    zapcc(cold): 0.2
    zapcc(hot): 0.04
    
    
    Run

so, not a replacement for what tcc does, but i can recommend it for when you 
want a 'real' compiler.
