Update CPU optimization flags for Sun Studio to the previous decade.
Also use -xO5 instead of -xO2; everything seems to work under -xO5 on x86-32 and x86-64 with my version of Sun Studio. Curiously, several things are miscompiled with -xO2! Definitely doesn't give me positive feelings about this optimizer.
