It's Simultaneous_music_iterator::pending_moment()

I moved everything but the problematic function to another file.  I'm  
attaching the files.  simultaneous-music-iterator-O1.s is compiled  
with -O1, simultaneous-music-iterator-O2.s is compiled with -O2.

That's x64_64 assembly.  Please let me know if you want i386 assembly.

I'll try playing with the C++ code.  That may give us a workaround for  
Lilypond and a compact example for reporting to GCC developers.
