6575685987 Update tests for Ddot 
The loops in Ddot are unrolled 2x now but might be changed to 4x in the
future so include more vector sizes to cover more possible states.

266f56a1bd asm: add appengine build tags

5b84ddfb9d Make generated complex drop-ins 
Again this is to allow simpler code generation of other BLAS routines.

b5fa43ce0f Make generated single precision drop-ins 
If single precision asm versions are needed the generate script will
need to be modified. This change allows code generated single precision
BLAS routines to be easier to make.

5d1c97461a Add noasm build tag 
This allows easy benchmarking against the pure pure Go implementation
and also provides a way to easily assess compiler improvements.

e.g.

	$ cd $GOPATH/src/github.com/gonum/blas/native
	$ go test -bench . > asm.txt
	$ go test -tags noasm -bench . > noasm.txt
	$ benchcmp noasm.txt asm.txt
