Simon Marchi c077c5802c binutils/readelf: decode AMDGPU-specific e_flags 
Decode and print the AMDGPU-specific fields of e_flags, as documented
here:

  https://llvm.org/docs/AMDGPUUsage.html#header

That is:

 - The specific GPU model
 - Whether the xnack and sramecc features are enabled

The result looks like:

-  Flags:                             0x52f
+  Flags:                             0x52f, gfx906, xnack any, sramecc any

The flags for the "HSA" OS ABI are properly versioned and documented on
that page.  But the NONE, PAL and MESA3D OS ABIs are not well documented
nor versioned.  Taking a peek at the LLVM source code, we see that they
encode their flags the same way as HSA v3.  For example, for PAL:

  c8b614cd74/llvm/lib/Target/AMDGPU/MCTargetDesc/AMDGPUTargetStreamer.cpp (L601)

So for those other OS ABIs, we read them the same as HSA v3.

binutils/ChangeLog:

	* readelf.c: Include elf/amdgcn.h.
	(decode_AMDGPU_machine_flags): New.
	(get_machine_flags): Handle flags for EM_AMDGPU machine type.

include/ChangeLog:

	* elf/amdgcn.h: Add EF_AMDGPU_MACH_AMDGCN_* and
	EF_AMDGPU_FEATURE_* defines.
