PPC: convert Altivec FFT to pure assembler

On PPC a leaf function has a 288-byte red zone below the stack pointer,
sparing these functions the chore of setting up a full stack frame.

When a function call is disguised within an inline asm block, the
compiler might not adjust the stack pointer as required before a...

PPC: add _interleave versions of fft{4,6,16}_altivec

This removes the need for a post-swizzle with the small FFTs.

1) remove TBL support in PPC performance. It's much more useful to use the
PMCs, and with Apple's CHUD it's fairly easy too. No reason to keep useless
code around
2) make the PPC perf stuff a configure option
3) make put_pixels16_altivec a bit faster by unrolling the loop by 4...
