Extension of D112504. Lower amdgpu printf to `__llvm_omp_vprintf` which takes the same const char*, void* arguments as cuda vprintf and also passes the size of the void* alloca which will be needed by a non-stub implementation of `__llvm_omp_vprintf` for amdgpu. This removes the amdgpu link error on any printf in a target region in favour of silently compiling code that doesn't print anything to stdout.
