Further changes to aac-he decoding. Refactor and rearrange dct tabs to be able to use consecutive addresses (this allows additional optimization for ARM through ldm-usage). Define a macro for identical butterfly operations and exchange 2 butterflyies with less compex operations.

Submit FS#11461. Major speedup for aac he profile (PP5002 +20%, PP5020 +15%, PP5022 +19%, MCF5249 +35%, MCF5250 +80%), still not realtime on most targets though. This change does a lot of refactoring in the sbr filters and the dct, switching to our optimized codeclib fft and tweaking IRAM usage.
