We are planning on making LTO the default compilation mode for offloading. In order to make sure it works we should run these tests on the test suite. AMDGPU already uses the LTO compilation path for its linking, but in LTO mode it also links the static library late. Performing LTO requires the static library to be built, if we make the change this will be a hard requirement and the old bitcode library will go away. This means users will need to use either a two-step build or a runtimes build for libomptarget. Reviewed By: JonChesterfield Differential Revision: https://reviews.llvm.org/D127512
