[opus] [RFC PATCHv3] Encode optimize using libNe10

[Viswanath Puttagunta]

Changes from RFC PATCH v2

- fixed compile issue when just compiling for --enable-intrinsics
  for ARMv7 without NE10

- Notes for NE10:
  - All compile/link warnings are now in upstream NE10
  - Only patch pending upstream in NE10 is the one that
    needs to add -funsafe-math-optimizations for ARMv7
    targets.
  - Phil Wang @ ARM is working on getting this fixed.
  - Note that even without this patch, stuff should compile
    and link without any warnings and run without errors
  - Only that for ARMv7 targets performance will not be
    improved.
  - For my performance testing, see my wip Ne10 branch
    below that applies -funsafe-math-optimizations
