Browse Source 
Passed building isac_neon and modules_unittests on Android ARMv7.
Passed modules_unittests with following filters:
  --gtest_filter=FiltersTest*
  --gtest_filter=LpcMaskingModelTest*
  --gtest_filter=TransformTest*
  --gtest_filter=FilterBanksTest*

WebRtcIsacfix_CalculateResidualEnergyNeon is removed, refer more in
