(pytorch#54) Refactor LLVMCodeGen to compile kernel in constructor Cmake integration to PT codebase (pytorch#28) With this change our code blends with the usual PyTorch code and is built the usual way. I added a cmake option to specify where to look for LLVM, if it's not specified, LLVM is not used. An example of invocation (from the root of pytorch repo): ``` USE_LLVM=/path/to/llvm9/install python setup.py develop ``` This command will build libtorch.{a,so} and other libraries, and tensorexpr code will be a part of it. The tests will be built in build/bin/test_tensorexpr (I've ported only one test so far). So, invocation of the tests will be: ``` build/bin/test_tensorexpr ``` Remove old padded_buffer.{cpp,h}.
