[opus] [RFC PATCH v2]: Ne10 fft fixed and previous 0/8]

[Viswanath Puttagunta]

Hi All,

As per Timothy's suggestion, disabling mdct_forward
for fixed point. Only effects
armv7,armv8: Extend fixed fft NE10 optimizations to mdct

Rest of patches are same as in [1]

For reference, latest wip code for opus is at [2]

Still working with NE10 team at ARM to get corner cases of
mdct_forward. Will update with another patch
when issue in NE10 gets fixed.

Regards,
Vish

Jonathan Lennox (1):
  Intrinsics/RTCD related fixes. Mostly x86

Viswanath Puttagunta (7):
  armv7(float): Optimize encode usecase using NE10 library
  armv7(float): Optimize decode usecase using NE10 library
  aarch64: Enable intrinsics for aarch64
  aarch64: celt_pitch_xcorr: Fixed point intrinsics
  armv7,armv8: Optimize fixed point fft using NE10 library
  armv7,armv8: Extend fixed fft NE10 optimizations to mdct
  test_unit_dft: Add nfft = 60, 240, 480 tests
