// Exposes the family of BLAS routines as pre-canned high performance calls for
// use in conjunction with the StreamExecutor abstraction.
//
// Note that this interface is optionally supported by platforms; see
// StreamExecutor::SupportsBlas() for details.
//
// This abstraction makes it simple to entrain BLAS operations on GPU data into
// a Stream -- users typically will not use this API directly, but will use the
// Stream builder methods to entrain these operations "under the hood". For
// example:
//
//  DeviceMemory<float> x = stream_exec->AllocateArray<float>(1024);
//  DeviceMemory<float> y = stream_exec->AllocateArray<float>(1024);
//  // ... populate x and y ...
//  Stream stream{stream_exec};
//  stream
//    .Init()
//    .ThenBlasAxpy(1024, 5.5, x, 1, &y, 1);
//  SE_CHECK_OK(stream.BlockHostUntilDone());
//
// By using stream operations in this manner the user can easily intermix custom
// kernel launches (via StreamExecutor::ThenLaunch()) with these pre-canned BLAS
// routines.
