codeclib: inline assembler for fft4 and fft8 on coldfire, small 0.2-0.3MHz speedup with gcc 3.4, larger 0.6-0.8MHz speedup with gcc 4.4/4.5

Rearrange and remove some manual register assignments, make use of pointer address increments for free on arm, and remove macros in favour of explicit inline fns. also add memory clobbers to all uses of stm in inline asm. appears to resolve issues with codeclib failing to work as expected when using ARM_ASM optimisations on targets with native position independent code (e.g. android rockbox targets, but also tremor on non-rockbox targets that has been patched with the fastermdct patches)

Adding ICODE for imdct (and its constituent ifft bits) gives 0.5MHz boost on arm (ipod video) and about 5MHz boost on coldfire (H120)

split_radix_permutation also unused (since now a hardcoded table) - but left intact so we can/could regenerate the table
