Valentin Korenblit 29f04d7934 package/llvm: enable AMDGPU
The AMDGPU backend provides ISA code generation for AMD GPU's,
starting with the R600 family up until the current GCN families.

It should not be confused with the AMDGPU Linux kernel DRM driver.

For more info: https://llvm.org/docs/AMDGPUUsage.html
