This patch introduces startup code for executing `main` on a device compiled for the GPU. We will primarily use this to run standalone integration tests on the GPU. The actual execution of this routine will need to be provided by a `loader` utility to bootstrap execution on the GPU. Reviewed By: sivachandra Differential Revision: https://reviews.llvm.org/D143212
