It would help compilation time a little bit, but generating the
assembly code and running the entire assembler is a fairly small
percentage of the overall compilation time--e.g., 3%.  It's worth
doing a fair amount of work to speed up compilation by 3%, but linking
the assembler into gcc would be an enormous amount of work.  I would
certainly support somebody who wants to tackle it, but I don't think
it's very high up the priority list for the overall project.
