For powerpc-apple-darwin, most of the time is being taking in get_cse_reg_info. But I will note that
powerpc-apple-darwin is now faster than even the 3.3 release or even Apple's 3.3
Hmm I noticed something, for 3.3.1 20030707 on i686-pc-linux-gnu, the speed of the compile is fast
but on a released version of 3.3.3 it is just as slow as 3.4.0, so there was a patch between them which
made this slower.
