Fangrui Song 8e0d5ac715 [llvm-readobj] Only allow 4-byte pr_data 
Summary: AMD64 psABI says: "The pr_data field of each property contains a 4-byte unsigned integer." Thus we don't need to handle 8-byte pr_data.

Jordan Rupprecht 4f36c7ad90 [llvm-readobj] Implement LLVM style printer for --notes 
Summary:
Port the GNU style printNotes method to the LLVMStyle subclass.

This is basically just a heavy refactor so that the note parsing/formatting logic from the GNUStyle::printNotes can be shared with LLVMStyle::printNotes.

Alexander Ivchenko ab60a2823f [llvm-readobj] Support GNU_PROPERTY_X86_FEATURE_1_AND notes in .note.gnu.property 
Resubmit of r333424. This version contains the fix for fails found by buildbots
on some targets.

This patch allows parsing GNU_PROPERTY_X86_FEATURE_1_AND
notes in .note.gnu.property sections. These notes
indicate that the object file is built to support Intel CET.
