> This PR introduces support for generalized buffer by creating SPIRV type structure and arrays in the generated module. Most of the implementation references the OpenCL Hat builder. The SPIR-V module assumes the same memory layout as the java buffer object, provided there is not additional customized padding between fields. Also, generated dependent functions from callgraph instead of using code model to resolve the issue where private functions can't be accessed.
