e1b01d4608 Remove floor0 stuff from IRAM. Results in a tiny speed decrease for files encoded with 6+ year old versions of the Xiph encoder, but saves IRAM which can be better used elsewhere. Thanks Nils Wallmenius in FS#7832 for the idea.

ed945e31c1 Slight speedup for the APE filters. Most noticeable on coldfire (+3.5% for -c2000), but also helps on the arm targets (+0.9% for -c2000 on PP5002). This transformation is oveflow safe, as absres < 2^24 is guaranteed.

2557251351 Correctly implement remaining portions of ffmpeg's r8627 that I'd forgotten about. This fixes a table overflow in low bitrate files that use noise coding, and in theory should be substantial improvement, but I haven't found any files were it makes a difference.

8cfbd3604f Use cookies for thread identification instead of pointers directly which gives a buffer against wrongly identifying a thread when the slot is recycled (which has been nagging me for awhile). A slot gets 255 uses before it repeats. Everything gets incompatible so a full update is required.

c1cd0469ca Implement mono predictor in assembler for coldfire, yielding a ~6% speedup for mono -c1000. Apply ideas gained from it back to the stereo predictor, saving 4 instructions. No speed increase for stereo, probably due to cache aliasing effects. * 80-column police.

113c285045 On ARM9TDMI (e.g. Gigabeat F) it's faster to use a ldr/str pair than add+ldmia/stmia for 2 registers. On ARM7TDMI a str pair is equally fast, so go for the simpler macro and use it for all ARMv4.

d7e4e54bcb Reorder instructions to avoid pipeline stalls on ARMv6 wherever possible (sometimes using different registers to allow this). Speeds up the predictor by almost 20% on ARMv6 (overall speedup for -c1000 is 5%), and might also help a bit on ARMv5. ARMv4 speed is unaffected.

3761c0108c Branch optimisation in both C (giving hints to gcc - verified using -fprofile-arcs and gcov) and asm files. Biggest effect on coldfire (-c1000: +8%, -c2000: +5%), but ARM also profits a bit (less than 1% on ARM7TDMI, around 1% on ARM1136).
