No matter how much you optimize your D code, you will only ever be able to use a subset of what assembly can do.
Such micro-optimizations give only marginal contribution to performance, which is mostly determined by choice of algorithms. The approach to write everything in assembly with manual optimizations is obsolete for many years, at least for desktop platforms. This is also one of the reasons, why optlink is translated to C.
I would like to see a linker written in D and see how it compares to optlink. But I would reserve making a decision on moving to another linker until I got some solid performance data. Some performance data for a D linker compiled with all three D compilers as well.
I only wanted to say, no matter what performance data we get, the linker can be optimized by choosing faster algorithms without tinkering with assembler.
