Startup timings

Just for information, on src/xemacs -geometry +0+0 -vanilla -q -kill which takes 3.12s on my laptop (which is horribly long) on an optimized, no debug, no kkcc, no mc-alloc compile, the biggest time users are: 79% init-x-win 7% startup-load-autoloads 6% init-mule-at-startup C startup (including pdump_load) is negligible btw. init-mule-at-startup is actually way slower (similar time to init-x-win) with cold disk cache too. I'm going to try to find why init-x-win is so slow. OG.
