I have opened a golang issue #16092 as follows:  
https://github.com/golang/go/issues/16092

I may have over-complicated it, but as well as the failure to use the load 
immediate instruction, I documented other suggestions that would make the code 
run faster as well as a method to eliminate the array bounds check for cases 
when the check is built-in to the loop as C# (sometimes) does for x86 code when 
one uses a specific formulation of a loop.  If able to be implemented, these 
changes would then apply to x86 code as well due to reduction of register use, 
and could potentially make golang code run as fast as C/C++ as compared in the 
issue.
