[flac-dev] 1.21 vs 1.3 encoding speed

I'm on a Mac and I'm noticing that encoding via the flac command line is
significantly slower with version 1.3.0 than 1.2.1. I'm encoding a 24/96
file to flac, both from wav and aiff and both formats are showing the same
speed decrease when using 1.3.0.

To give an idea of the speed decrease, encoding at flac level 8:

24/96 wav file
1.21: 61.05 seconds. ratio=0.690
1.3: 222.48 seconds. ratio=0.690

smaller 16/44.1 wav file
1.21: 14.28 seconds. ratio=0.487
1.3: 51.21 seconds. ratio=0.487

Also, 1.2.1 will not encode an aiff-c file, but 1.3.0 will. Is this change
documented anywhere?
