silk_burg_analysis() could return a slightly negative value on zero
input, which would cause a negative, which the log didn't like.

The existing code in vec_avx.h produced
  warning: dereferencing type-punned pointer will break
   strict-aliasing rules
 with gcc 6.4.0.
We already had a macro to work around this within the rules of the
 C standard, but trying to use that here does not get optimized
 into a single MOVD like we were hoping.
Replacing it with memcpy() instead does get optimized correctly,
 but requires switching from a macro to an inline function in order
 to be able to declare a local variable and return a value.
We already have such an inline function in NSQ_del_dec_avx2.c, so
 hoist that out and use it everywhere, and then convert vec_avx.h
 to use it also.

Also skip the first loss values being generated since they're
biased towards "not lost" due to the initialization.

Fails ubsan because memcpy declares args as non-null

No longer needed now that PLC is trained with PyTorch stack

Should handle the history in a more consistent way.
Slightly increase the model size and re-enable biased band loss in
training.

mostly untested

Should match the TF2 code, but mostly untested

Also default to disabling dnn float debugging

Still don't quite know what I'm doing

Compilers sometimes replace vmlaq*() with fmul+fadd instead of fmla.
Trying to use vfmaq*() instead when possible.

Finished adversarial training on 800k model. Also, move weights to a new
location.

Adds RTCD tables for compute_activation() and compute_conv2d()
