Get rid of .rept in inline asm() blocks where possible. Using .rept causes gcc to wrongly estimate the size of the asm(), leading to (potential) compilation problems. This is necessary for the upcoming restructuring, and should fix ARMv6+ sim builds as well. No functional change.

APE: Fused vector math for the filters on ARMv5te. Speedup on Cowon D2 is ~4% for -c2000..-c4000 (less for -c5000). Thanks to Frank Gevaerts for testing.

Resurrect the ARM7 16-bit packed vector addition/subtraction for ARMv5, giving a nice speedup for the higher compression levels (tested on Cowon D2).

Several tweaks and cleanups: * Use .rept instead of repeated macros for repeating blocks. * Use MUL (variant) instead of MLA (variant) in the first step of the ARM scalarproduct() if there's no loop. * Unroll ARM assembler functions to 32 where not already done, plus the generic scalarproduct().

Add preliminary ARMv5te optimisations (verified working, but can probably be sped up further), and fix a comment in the ARMv6 code.
