execution, we would immediately set it to the default runner of the
*local* FLR, even if the function was to be executed remotely. This
change postpones the resolution of the default runner until after the
function invocation has been routed to the FLR that will actually
execute it.

As a result, we avoid the pathological case where a GPU device using a
private threadpool (TF_GPU_THREAD_MODE=gpu_private) ends up running
all of the ops for the CPU-side input pipeline on the private
threadpool.

[TF:XLA:GPU] Allow the use of linear address when there are size one dimensions

The current implementation of EmitArrayElementAddress incorrectly concludes
that having a size one dimension in a tensor indicates broadcasting is needed
and the linear address can't be used to access the tensor. We fix this by
leaving LinearValidOnShape to decide whether the linear address can be used to

elementwise op kernels when other criteria are met.
