Log:
  MFC r337569: readelf: display NT_GNU_PROPERTY_TYPE_0 note name
  
  NT_GNU_PROPERTY_TYPE_0 in a .note.gnu.property section "contains a
  program property note which describes special handling requirements
  for linker and run-time loader." (from the System V Application Binary
  Interface - Linux Extensions")
  
  Intel CET uses two processor-specific program properties in
  NT_GNU_PROPERTY_TYPE_0: GNU_PROPERTY_X86_FEATURE_1_IBT to indicate that
  all executable sections are compatible with Indirect Branch Tracking,
  and GNU_PROPERTY_X86_FEATURE_1_SHSTK to indicate that sections are
  compatible with shadow stack.
  
  A later change should add decoding of the individual properties.
