Step 1 of re-namespace'ing StreamExecutor into ::stream_executor.
This moves everything inside of stream_executor/..., and leaves a
namespace alias into ::perftools::gputools. The next steps will clean
up users to use the new namespace.
This is mostly a mechanical change, but it also includes a bunch of
non-mechanical changes that ideally would be split out into separate
patches. Unfortunately they all sort of need to be shoved in here for
various reasons:
- forward declarations need to be in the same namespace as the actual
types, so we need to change all forward declarations of
StreamExecutor types in this one patch.
- Uses of these forward declarations need to be changed to the new
namespace (or otherwise we need to add a namespace alias to the
relevant header, but this is pretty ugly).
- Various initialization code needs to live in StreamExecutor's "real"
namespace, so all this needs to be changed.

Extend the stream interface ThenBlasGemmWithAlgorithm to support F16 matrix
multiplication with computation type FP32.
Extend the stream executor interface DoBlasGemmWithAlgorithm to support F16
GEMM with computation type FP32.
Extend the CPU IR emitter to handle F16 Dot instruction, and add F16 matrix
multiplication implementation to the CPU runtime.
Extend the GPU backend to handle FP16 GEMM Thunk.
Replicate the existing matrix multiplication test cases in
matrix_ops_simple_test and dot_operation_test for FP16.

cublas 8 adds the cublasGemmEx function, which lets you specify an
explicit "algorithm" for the computation. This functions as an opaque
tuning hint to cublas.
This patch adds support for cublasGemmEx to StreamExecutor, and wires up
XLA's GemmThunk to use the new function.
This patch does not add GEMM autotuning support in TensorFlow proper,
only XLA.
