How hard would it be to create a new backend in D?

So a Gentoo? Now since Gentoo has been mentioned some one is 
required to mention Arch in the responses.

The only benefit I would want from compiling everything myself 
instead of downloading precompiled binaries is that I could 
enable specific optimizations for my system. The only backends 
that have all those optimizations are GCC and LLVM. What other 
benefits do you see that are worth the hassle?

I think when talking about creating executables from source code 
its better to use the word build instead of compiling to describe 
that process. In order to build the program you need to compile 
and link. The last time I built debug version of DMD on my system 
around half of the time was spent linking so even if you can get 
a significantly faster backend the whole build time wont change 
significantly. You need to think about the whole pipeline if you 
want big changes.
