Vignesh Balasubramanian 6165001658 Bugfix and optimizations for ?AXPBYV API
- Updated the existing code-path for ?AXPBYV to
  reroute the inputs to the appropriate L1 kernel,
  based on the alpha and beta value. This is done
  in order to utilize sensible optimizations with
  regards to the compute and memory operations.

- Updated the typed API interface for ?AXPBYV to include
  an early exit condition(when n is 0, or when alpha is
  0 and beta is 1). Further updated this layer to query
  the right kernel from context, based on the input values
  of alpha and beta.

- Added the necessary L1 vector kernels(i.e, ?SETV, ?ADDV,
  ?SCALV, ?SCAL2V and ?COPYV) to be used as part of special
  case handling in ?AXPBYV.

- Moved the early return with negative increments from ?SCAL2V
  kernels to its typed API interface.

- Updated the zen, zen2 and zen3 context to include function
  pointers for all these vector kernels.

- Updated the existing ?AXPBYV vector kernels to handle only
  the required computation. Additional cleanup was done to
  these kernels.

- Added accuracy and memory tests for AVX2 kernels of ?SETV
  ?COPYV, ?ADDV, ?SCALV, ?SCAL2V, ?AXPYV and ?AXPBYV APIs

- Updated the existing thresholds in ?AXPBYV tests for complex
  types. This is due to the fact that every complex multiplication
  involves two mul ops and one add op. Further added test-cases
  for API level accuracy check, that includes special cases of
  alpha and beta.

- Decomposed the reference call to ?AXPBYV with several other
  L1 BLAS APIs(in case of the reference not supporting its own
  ?AXPBYV API). The decomposition is done to match the exact
  operations that is done in BLIS based on alpha and/or beta
  values. This ensures that we test for our own compliance.

For more information on sub-configurations and configuration families in BLIS, please read the Configuration Guide, which can be viewed in markdown-rendered form from the BLIS wiki page.

If you don't have time, or are impatient, take a look at the config_registry file in the top-level directory of the BLIS distribution. It contains a grammar-like mapping of configuration names, or families, to sub-configurations, which may be other families. Keep in mind that the / notation:

<config>: <config>/<name>

means that the kernel set associated with <name> should be made available to the configuration <config> if <config> is targeted at configure-time. (Some configurations borrow kernels from other configurations, and this is how we specify that requirement.)
