[Regression] snd_emu10k1 doesn't work after GCC 4.2 upgrade

[Yuriy Tsibizov]

I've re-checked this problem today and it seems to be a real gcc regression. I had more pessimistic optimisation flags ( -O ) in my first tests and snd_emu10k1 was running without problems. If I build it with -O2 (default value for -CURRENT, with __MAKE_CONF=/dev/null) it is broken (I checked it on my Audigy card and it shows different problems from Live!, because it uses different code paths in driver). snd_emu10kx is not broken with both -O and -O2. I can't tell for shure, but there was no bug reports about broken snd_emu10k1 with -O2 and old gcc.
