GAS really isn't a bottleneck on modern machines that have plenty of buffer cache.

I changed the GCC c-torture/compile.exp tests last year so that they just compiled 
rather than including the assembly step (ie. using -S instead of -c), thinking it 
would speed up those tests.  Over that large testsuite, the saving was less than 0.1%.

If you'd like to make something faster, work on the linker!
