TVM's relation to XLA---------------------They has different abstraction level.XLA is a higher level tensor algebra DSL, the system defines codegen and loop transformationrules for each kernels. TVM is an low level array index based DSL that give the loop transformationprimitives to the user. In terms of design philosophy, TVM aims to be directly used by developersand provide general support for different framework via DLPack.See also [This Issue](https://github.com/dmlc/tvm/issues/151)TVM's relation to libDNN cuDNN------------------------------TVM can incoporate these library as external calls. One goal of TVM is to be able togenerate high performing kernels. We will evolve TVM an incremental manner aswe learn from the technics of manual kernel crafting and add these as primitives in DSL.
